I would like to share my opinion on your choice. I agree that we don't spend a lot of time in our rooms, but I think that the most important decision (well, price too) is where you plan on spending the most time on property. If you are planning on spending more time in the Magic Kingdom, then I would suggest that you look at resorts that are closer [or have more convenient transportation] to that park. Deluxe, as some have said,
usually mean a shorter time from resort to park, but it depends on what resort and what park. Not sure if you have small children, but location is even more important if you want to return to your resort to give the kids a rest.
I don't think this was mentioned, but why not split your trip between 2 resorts? We did it, it's not that big of a deal as the CM's move your luggage while you're at the parks. This way if you're torn between 2 resorts, or you want to move your home base as you focus on different parks, you can. Plus then you get to experience 2 resorts in 1 trip!
The resorts are great; visited several but only have stayed at 2 resorts in all our trips. I guess you'll figure out what my favorite is.
