Yes, Comfort Suites is an option as well. you just have to walk across the street and through Atlantis lobby. The price I got at travelzoo is only $100 more than the CS and I can get bands for the 5 people in my party rather than 4. Total with taxes and fees - $266.
I guess with Atlantis you either love it or hate it. We loved the pools, aquarium, beach. Inside it is a bit overdone and the food was not great, but not bad either, kind of like WDW food, trying to feed thousands of people at the same time. I would go there again though. I'll go anywhere with pristine beach access to that crystal clear blue water~!!!!
BTW, with travelzoo, there is a $25 cancellation fee and if for some reason we don't hit that port during the cruise, there is no refund. You will forfiet the 1 night's deposit.
Trying for a day room on the day of arrival is another option. We just wanted to be guaranteed a room since the kids are really looking forward to that.
