Personally, I love the Pop Century.
For me, going to Disney is hardly about the resorts. I want a comfortable place to sleep, kick my feet up, be able to grab coffee, a snack, or maybe even a meal at, but that's really all I need. The Values do that just as well as the deluxe's do. They're not as fancy, not as many dining options, not as nice a pool, but you can hotel hop to get the chance to see and enjoy what the deluxe hotels have to offer. For a place to sleep at night and have a few ammenities readily available, values more than get the job done, for me at least.
My parents (who aren't even moderately snobby, at all, but rather just stuck in their ways really, and always stay at deluxe's, or stay at the nicest hotels on other vacations) actually booked at the Pop Century two years ago and were absolutely shocked at how much they enjoyed it... and said they'll probably just continue to stay there because it's so cheap and gets the job done.
My two cents... :shrug:
