Just back from CSR! We faxed ahead with details about our special event grovelling for Cabana 9b, and not only did they honour the request but we had a double aspect room with water view. Also, mid-way between birthday and anniversary celebrations we returned from dinner to find two bunches of balloons (one anniversary, one birthday), a birthday card for me from Princess Aurora and an anniversary card from Mickey and Minnie (both with large signed photos). I hadn't mentioned it on check-in, and we didn't have any cards up so they must have noted it from the fax.
I'll do a proper trip report when I have time but here's a couple of points:
The hairdryers in the room are powerful enough to use (unlike
Disneyland Paris!) so no need to take your own.
If you need extra towels and don't want to wait for mousekeeping, send someone to the pool (the towels are interchangeable).
IMHO the Maya Grill is lovely for dinner, but we found the service slow for breakfast. I know its a serve yourself buffet, but at one point our waiter diappeared from sight for a good 25 mins leaving us gasping for drinks.
Pepper Market can be a very annoying place to eat! OK, you do get your table assigned (so no worries about being left standing with trays of food) and drinks brought to your table (again, sometimes a wait), but there is no separate ordering/collection point at each counter, leaving a disorganised group of people half waiting for their orders half waiting to place an order. And generally only one person per counter so if they are flipping burgers you have to wait till they come up to the front to order. The food was only OK - we preferred eating out, more food and better value.
On size, we didn't find it that spread out (perhaps because we were so conveniently sited!) - anyone who has stayed at Centerparcs or similar will find it perfectly manageable.
