On our Feb 2013 trip stayed in one of the Lion King suites in building 10, for us it worked out great! We had 5 people, my DD, DW, myself and then also my parents. My DD wanted to sleep with grandma so they took the sofa bed, my dad slept on the murphy bed table, so my DW and I got the "master" bedroom.
We are going back again in Feb 2015, part of the trip it is going to be just 3 of us (me, DD, DW), but for another part my parents are going to join us since they will be wintering in FL. So while my parents are with us we will be getting a suite again at AoA, we are thinking Nemo this time around. When is just the 3 of us we will probably stay at a different resort just for a change.
