I have stayed at both. Neither will disppoint. Seriously, if you are not going to be in the room much-stay at POP and use the extra cash elsewhere. POP has a great food court, cute pools and splash pad and nice playground. If your kids are younger for sure. (Although DD is 11 and we have stayed at value, mod and deluxe and she always wants to go POP) Now for CBR - room a bit bigger (doesn't matter much if you only sleep, shower there), the main pool is great (zero entry and 2 waterslides(no slides at POP) and nice beachy feel-hammocks, sand beaches and a few playgrounds. But, if you are not having a "resort day" go POP.
Just my 2 cents.
As I said to open- you cannot go wrong here with either choice.
Good luck- Have fun
