The accommodations at the Atlantis were very luxurious. The reason for this was because the resort is surrounded in paradise, which makes it very pleasant. The staff was also very helpful and friendly, and they bent over backwards for us. The food was also great, as there were many restaurants to chose from. However, these restaurants were very pricey, so I do suggest that you buy the meal plan prior to your stay at the Atlantis. The meal plan includes either two meals a day (Gourmet plan) or three meals a day (American plan). We chose the American plan, which included three meals a day, but it was too much. The food is served in very large portions, so I suggest that you get the Gourmet meal plan, as two meals a day at Atlantis is plenty!!! We could hardly eat the two meals a day, let alone three. The room service was very nice and the room included a safe to store important items in (passports wallets, etc.).
The Atlantis also includes a fitness center, spa, and other many enjoyable activities, such as parasailing and banana boating. These activities are not free, though. I suggest using the fitness center because it was very nice, but I am not sure of the price.
One thing we found very helpful was the Hospitality Cavern, which was a facility (equipped with showers, dressing rooms lockers, etc.) for people who had checked out earlier that day and wanted to stay on the property until their flight (if it's in the afternoon). We found this very helpful because we went swimming in all the pools and onto the beach right before we left. We knew that our things were safe because they were locked up in an individual locker. Once we were finished swimming, we were then able to shower before hitting the airport. The Atlantis was one of the best hotels that I have ever stayed at because of its many perks.
