We've been going for a while too! This summer, I talked my DH into 15 days at Disney! It was great!!!! After we got back, I was lost without planning another trip - so he gave me the go-ahead for our "annual" Christmas trip!!! Yeah!!! Now I've got to talk him into next summer!!!
As far as hotels, for budget trips, we like Pop Century! They are neat, clean, and lots of fun! (We've also stayed at All Star Movies a few times, and All Star Music once - for a budget trip, they are fine!) For the moderates, we've stayed at Port Orleans FQ, and Coronado Springs! Both of those were very nice too! And the deluxes are oh so nice - my DD LOVED Boardwalk Inn this past June! She loved the waterslide!!!! We've also stayed at the Polynesian, Contemporary, Grand Floridian - all very nice.
I'd suggest you study the websites - wdwig.com has some great info on the different hotels, as well as slide shows of the rooms & decor. Then you can decide which theme appeals to you most! Good luck!!!!! Have a great trip!!
