Having stayed at both, I HIGHLY recommend POP for families with small children. Coronado and Caribbean both are huge properties. Great pool areas, but long walks/stroller pushes to just about everywhere. POP is more centralized with a very nice pools. We are about to start planning our next trip and just had the discussion today about benefits of resorts. While Coronado and Caribbean are beautiful resorts, we would rather stay longer at a value, we prefer ASMovies, than the scenic upgrade at the moderates. The only real option I'd consider is probably one of Yacht/Beach/Boardwalk due to the ability to walk to EPCOT, boat to Hollywood Studios, or monorail to Magic Kingdom via EPCOT.
