Something you might consider - you're staying in the MK area for part of your stay and it might be nice to stay in a toally different resort area (Epcot) for the latter part. Room views removed from consideration, overall, there is a ton more to do at the Epcot resorts.
The great thing is you can't go wrong with either choice. Enjoy!
