We just returned from VB and the WDW. I stayed 2 nights at Pop Century with my 2 kids(before meeting up with the rest of my family) I think the higher floors are more relaxing.........just my opinion. We were in the 70's building on the 4th floor across from the big wheel. The other side of the building faces the water and that would be nice as well. I think we were a 3 minute walk to everything............food court, pool, transportation, parking lot. In my opinion, I think a first floor pool room might be a bit noisier.
My DD(14) loved the Hippy Dippy Pool. She was also the family photo journalist and took lots of digital pics and did some camcordering as well. We ate one meal in the food court which was good. I had the sloppy joe and my kids shared the chicken fingers. The next evening, we stopped there and picked up a piece of tye dyed cheesecake for a late night dessert........yummy!
With a two week stay, I would probably change resorts midway. But, that's just because I like to try different resorts. Disney will transfer your bags for you. It is really convenient!
