In college, I went with friends and we stayed at All-Star Movies. The decor was just too over top cheesy for me, but the price was great (no preferred rooms back then so we got one close to the main hall but away from the pool which was perfect). Stayed at the Music resort in a preferred room a few years back, and it too was cheesy and the pool noise was bothersome, but not enough to trade it for the 20 minute walk of a quiet room. And the staff were amazing. All just super kind and friendly and helpful.
I'm not really one to care about my room whilst at Disney--I'm barely there and never eat at the resort restaurants (that's what the World Showcase is for, right?). So for the price and convenience I'm not going to turn down the All-Stars, but I'd stay at Sports if I went value again as it is the first stop on the bus route.
The second half of that same trip, I stayed at Pop century and was completely disappointed. My room was horrible. A crack in the ceiling, mold & mildew in the bathroom and vanity, fraying towels, a live cockroach, ripped and peeling wallpaper, paper thin walls that forced me to hear the lovemaking going on next door (seriously, who has energy for that after a day in the parks?), plus less than friendly or helpful staff (with the exception of one standout Barb, I remember her name because she was so awesome). Smokers everywhere were completely ignoring the no smoking signs; one smoker was actually pointedly blowing smoke at the no smoking sign and cast members walked by without saying a word. Best thing about the grounds was I saw tons of bunnies every morning and evening which was the only good I found at Pop Century. I took pictures of my room and sent them to Disney in a very friendly but disappointed letter. Never heard back. But from reviews by other subsonic folks, perhaps my room and experience was irregular.
In Jan 2012, I magically got to stay at the Caribbean Beach. I had used my Hilton Vacation points to book my family in a 3 bedroom condo on International Dr (like we had done in 2008 & 2010). My parents take the master, I was in the smaller room (with two double beds), my older sis took the lock-off 3rd bedroom, and my younger brother slept on the pull out in the living room. But as usual when we travel as adults together, we all got sick and since my bro was the most sick (missed a day and a half in the parks whilst a nasty flu bug ran its course), I gave him the extra bed in my room and from my iPhone whilst walking round in Frontierland booked a room for myself for the last 2 days at all-star movies. When I tried to check-in, the CM said there was a note on my reservation and she had to make a call. I was worried that something had gone wrong, but instead she told me that I had been upgraded to a Caribbean Beach preferred room. She gave me a taxi voucher and sent me off to CB where they seriously took care of me. I was so totally impressed. Felt kinda like royalty so I can only imagine what it must be like to stay at one of the deluxe resorts. The room design was pretty much exactly like the All-Stars (maybe a teeny bit bigger), but the service was so much better. The bus line for getting to the park was no problem, but the return from EPCOT during EMH was considerable. I was in line way outside the designated queue area but made it on the third bus (standing because I gave my seat to a woman holding a sleeping toddler--she definitely needed & appreciated it more than I). I think the line just looked longer due to all the strollers taking up so much space.
For my next trip, I'm staying at Port Orleans - Riverside for the first time and apparently I'm going to love it and staying there will make me an official subsonic-er apparently since it seems to be a favorite of many posters.

I would love to stay at the Poly one day, but I just can't bring myself to spend the money on a room I spend so little time in...
