My family was on the Wonder in December and all 8 of us took a taxi over to Atlantis for $4-5 a person. I studied up on the Disboards so I was prepared to get a day room if available. I stopped at the main lobby at Atlantis and they said to get a day room you can get one at any of the Towers you want but you have to walk to that reservation desk to inquire about one. We decided to check Coral Towers since I thought it was the closest to the beach, pools, and casino to make everyone happy in our group. I had read that most of the day rooms were a loooonnng walk away in the hotel so I was worried that it would be worth it since we had two senior citizen moms with us. I checked in at the Coral Towers desk and told them what I wanted. She pointed to go to the in house phone across the lobby and call the reservation desk. It was like a phone booth you went into and I called and the lady on the phone said for a party of 8 I had to get two rooms at $150 each plus taxes and fees. The fees are accessed per person but not sure on age limit. Well, we got this far and two day rooms were about the same as what it was to get an overnight room in advance so I took the 2 day rooms. Then I was to proceed back to the desk across the room again to formally check in. When I got there and told her I was there for 2 day rooms she looked at me puzzled and quietly said "oh, you should've told me originally you had 8 people". She said let me cancel one for you and did it very discretely and was watching over her back all the time with other employees coming and going. She did cancel one room and gave us 8 cards for one room. I asked for a room very close if possible and we got a room three rooms down from the hallway (very short walking distance from the Coral Towers lobby.
We had a great time but it was cooler the day we were there. Go early and see everything but also relax and enjoy!!! My four kids (5-13) loved looking at the all the aquariums and the swinging bridge. The beach water temp was very cold. We were asked about hair braiding and jet ski rentals. I had read that some people were appalled by being asked repeatedly. We didn't think it was any big deal, we just said no 3-4 times and it was done. The resort itself is worth seeing in our opinion and we would recommend it.
Sorry this is lengthy but hope this helps, let me know if you have any specific questions!!!
