Well each resort offers something totally different.
Personally, I would choose PORR, because of the flexibility of the resort: you can stay in either a Bayou type home or a mansion style. The grounds for this resort are AMAZING, and the atmosphere is unparalleled, I really think it is a gem in the resort system.
Nearby PORFQ is wonderful too, although I can't comment too much because I haven't stayed there. When I stayed at PORR (well, Dixie Landings back then!) we took a trip down the river to FQ and tried out the pool, which was great!
My last trip, with school, we stayed at CB. This resort is huge, and the themeing is also great. I have written before, my favorite part about this resort is the island in the center of the resort...I really feel like I am in the Carribean on a lost island! This resort is also great because it affords losts of quiet places and hideaways to read a good book!
Also, on Coronado Springs...I haven't stayed there, so I can't help you out on that one..sorry! So I guess if I were you, I would definately stay at PORR!!!!:sohappy:
