We loved AB - we are smokers

, don't shoot us now - and so they put us in building 18. Handy for the food court though!! I have to say, nobody should worry, regardless of the accom. Whether it's AB or the mansions, everything was first class. I'll get a proper review out once we recover from our jet lag, but AB was FAB. Lush greenery, great room maintenance, nice people all round.
If anyone has a complaint, they must be used to 5 star service year round. Room was average size, but fine. All have the mini-fridge (holds 24 cans of Bud and some soda). One thing I would mention - there was just the 2 of us and we are average size or less - we did find the bed kind of small but very comfortable. If there are only 2 of you, it might be worth the extra for a king bed if available.
Word of warning; the resort is full to capacity, therefore, although the staff will try to accommodate your requests (they met ours), it might not always be possible.
TIPS: buy the mugs; hire a boat; quiet pools are not quiet between 2-6 pm! (But great at 9 am and 11 pm)! ; be good to your housekeeper (we came back one day and Eeyore and a couple of Teds had switched the TV on and were watching the Disney Channel from the bed)! ; be prepared for long waits (over 30 minutes) from the parks back to the Hotel - consider catching a bus to the FQ (it's only a 10 minute walk to POR, and a nice walk at that); explore the property fully; see Pianoman Bob between Wednesday and Sunday in the bar! Feed the ducks and try the boat to DTD.
