In short: Five genuine all-inclusive hotels on Kos: Astir Odysseus at Tigaki for brand spirits by the beach, the two Cabana hotels in Kardamena for à la carte dinners, Atlantica Belvedere for adults-only calm and Mitsis Norida for service around the clock. Five half-board alternatives follow, including the adults-only D'Andrea Lagoon, OKU Kos and Diamond Deluxe.
Kos has long beaches on both coasts and no shortage of all-inclusive resorts.
At the luxury end, however, the choice narrows quickly: only five hotels on the island sell a genuine all-inclusive package that lives up to the name. So this guide does not stop at five. After them come the strongest luxury hotels we found that sell half board instead, each clearly marked as an alternative.

1Astir Odysseus Kos Resort and Spa
Kos, Greece
Food & restaurants: 36 of 36 mentions positive · Service & staff: 34 of 34 mentions positive
Why this rank: Guests rate it consistently well, and the drinks go further than at the two Cabana hotels: international brand spirits and the minibar are included. What holds it back is à la carte, with a single dinner at Argo and only on stays of seven nights or more.
2Cabana Blu Hotel & Suites
Kos, Greece
Why this rank: A package guests praise by name: two à la carte restaurants for dinner, wine, draught beer and cocktails, and the beach about 20 metres away. Branded spirits cost extra, however, and drinks after 23:00 are charged.
3Cabana White Boutique Hotel
Kos, Greece
Why this rank: Guests call the package very complete, and Elia Beach Restaurant comes on top of the two à la carte restaurants shared with Cabana Blu. The trade-off for the small format is that buffet meals are served at Cabana Blu, reached by shuttle, and branded spirits are not included.
4Atlantica Belvedere Resort - Adults Only
Kos, Greece
Why this rank: Adults-only, on a hillside above a sandy beach, with every restaurant and bar part of the all-inclusive. Guests praise the food, but the hotel publishes neither the package's hours nor whether premium drinks are included, and à la carte stops at one dinner at Thalassa on stays of five nights or more.
5Mitsis Norida
Kos, Greece
Why this rank: Ultra all-inclusive with food and drink around the clock, from a 4am early breakfast to a light late-night buffet, plus three à la carte restaurants. Guests praise the food. It is a large family resort, though, and premium spirits are not confirmed as included.
6D' Andrea Lagoon All Suites - Adults Only
Kos, Greece
Service & staff: 45 of 45 mentions positive · Food & restaurants: 27 of 29 mentions positive
Why this rank: Does not sell all-inclusive: the sources we found show breakfast and half board only. It earns its place as an alternative with adults-only calm, a large lagoon pool and direct beach access in Marmari.
7Service & staff: 30 of 31 mentions positive · Food & restaurants: 19 of 19 mentions positive
Why this rank: Sells breakfast, half board and full board, but not all-inclusive. An adults-only all-suite hotel with a wellness focus and direct access to the beach at Agios Fokas.
8OKU Kos
Kos, Greece
Food & restaurants: 51 of 65 mentions positive · Service & staff: 49 of 53 mentions positive
Why this rank: OKU sells breakfast and half board, not all-inclusive. It is here for its adults-only, village-style layout, a private sandy beach and a full spa.
9Diamond Deluxe Hotel - Adults Only & Spa
Kos, Greece
Service & staff: 44 of 44 mentions positive · The rooms: 34 of 34 mentions positive
Why this rank: Breakfast and half board only, so no all-inclusive. Adults-only, with a lagoon-style pool and a private sandy beach in Lambi; some guests notice aircraft noise.
10Neptune Luxury Resort
Kos, Greece
Why this rank: The hotel itself confirms there is no all-inclusive, only bed and breakfast and half board. It is here for its art-filled gardens, several pools, beachfront access in Mastichari and a wide range of sports.
How we chose and ordered the hotels
We checked every hotel against its own website in October 2026, not just against a booking site. A hotel only counts as all-inclusive here if it sells a board under that name itself. For those five we also noted what the package actually covers: à la carte dinners, branded spirits, how late the bars serve and whether there is an ultra tier. Where a hotel publishes nothing on a point, we have left it blank rather than guessed.
The five all-inclusive hotels come first. The five alternatives follow, each marked in the list: they sell half board (KOIA also full board), and none of them sells all-inclusive. Within each group the hotels are ordered by guest score, which we use to sort the list but never print.
The criteria were the same for every hotel. It had to be a luxury hotel with enough guest reviews behind its score for that score to mean something, and the score had to clear our floor. Four-star hotels faced a higher floor than five-star ones.
Worth knowing about Kos
Kos is long and narrow. Kos Town and its harbour sit at the north-eastern tip, the airport lies inland towards the middle of the island, and where you stay decides how far you are from both.
The north coast – Tigaki, Marmari and Mastichari – is lined with long, open beaches. Astir Odysseus sits right on the beach at Tigaki, D'Andrea Lagoon is in Marmari and Neptune in Mastichari, where ferries leave for Kalymnos. The summer wind is felt most on this side of the island, which kitesurfers welcome and sunbathers notice.
Kardamena on the south coast is a resort town with a lively centre. Cabana Blu is on the beach a short walk from the village and Cabana White on its quieter outskirts. Atlantica Belvedere stands on a hillside above a sandy beach about four kilometres out, and Mitsis Norida lies on a Blue Flag pebble beach about five kilometres from town.
Around Kos Town you will find Diamond Deluxe in the Lambi area north of town and KOIA at Agios Fokas to the south-east. Several hotels in this guide are a fair way from Kos Town, so if evenings in town matter to you, budget for taxis or a hire car.
Hotels we reviewed but left out
Many more hotels went through the same review. Some sell all-inclusive but fell short of our floor; others are fine hotels that sell no all-inclusive at all. These are the ones most worth knowing about.
- Ikos Aria – a genuine all-inclusive from the Ikos brand, but too few reviews yet for its guest score to carry weight.
- Sovereign Beach Hotel – five stars and all-inclusive, but still a little short on reviews.
- Kouros Palace Active Lifestyle Hotel – all-inclusive and five stars, with too few reviews yet.
- Pelagos Suites Hotel & Spa – a five-star all-inclusive whose guest score sits right on our floor rather than above it.
- Grecotel LUXME Kos – sold as luxury all-inclusive, but below our guest-score floor.
- Mitsis Summer Palace – five-star all-inclusive with a guest score below our floor.
- Mosay All Suite Hotel – well liked by guests, but sells breakfast only; dinner is à la carte and there is no all-inclusive.
- White Rock of Kos Hotel – Adults Only – breakfast only on Booking and half board only through tour operators, with no all-inclusive.
A hotel missing from the list is not one we think poorly of. It means either that it does not sell all-inclusive, or that it did not clear our floor this time.
