We (husband, me, 1 and 3 year olds, grandparents) stayed in a 2 bedroom this past September. The resort is beautiful. I was skeptical b/c it was through a timeshare and we read some reviews that mentioned it was loud if you are near a trash chute and that there was some smell in some rooms. The inside is really well done and we didn't smell anything or hear anything once inside our room (it was low season though). Huge plus for the resort is the lazy river pool they have on-site. And it is on Disney property so the commute time to the parks is very short. They do have transportation to the the parks but we used our rental car so I cannot comment on their transportation.
The only negative I have was that the second bedroom was two doubles instead of queens which made for a very tight fit for my husband and me (we are used to a King). The master bedroom is a queen (or king?) though and it has a HUGE shower/bath area. Very nice.
We would stay there again! (Oh! And some rooms have a view of the fireworks from one of the parks. We did not have one of those rooms b/c my father-in-law requested a room with a view of the lake instead.
Hope this helps. Any specific questions feel free to ask!
