Hi!
For a 2 day stay (perhaps I'm reading your trip dates wrong), I'd move to save $450.
But, if you are staying longer, perhaps Carribean has FD or RO discount? I love POFQ, but with a 2 year old (my kids are now older) I wouldn't hesitate to switch from POFQ to CBR because CBR has a great kiddie pool area. It is gated and well guarded: older kids cannot get in (I can't remember the age cut off - or maybe it is by height). If you pay for a "Preferred" room you will be nice and close to both the food court, main bus stop, main pool (including kiddie pool), evening movie, evening marshmallow roast. If you can't get preferred, then there could be alot of walking - unless you have a car and don't frequent the food court more than, say, 1x a day.
Hope that helps! I really think the age of your child will = a great stay at CBR. (POFQ does have a kiddie pool area too - I think it has a few sprinklers - but the one at CBR is really nice. Having written all this, though, maybe 2 years old is too young to care about the nicer kiddie pool at CBR!).
