For us in order of importance:
We always request first floor as we have a stroller, and it really helps with the kids.
Sports building requests if you have preferred would be Surfs Up (1 and 6) and Touchdown (7 and 10).
Buildings 7 and 10 are refurbished and as I understand it 6 may be closed being renovated with building 1 open but un refurbished rooms.
At Pop we have been given rooms in the 70's section (Building 6 and 10) when booking standard in the last year. I like these as they are close to main food hall, Bus transport and Skyliner without the higher cost of preferred.
Enjoy your trip!
