You should request a daybed room (2 queens and a daybed), which is classified as standard view. There are only 39 daybed rooms, and there is no way to guarantee you will receive one. GCH allows 5 in all rooms, although this often means 2 queens and a sleeping bag

Roll away beds are not available. There are a limited number of cribs available, folding "play pens" are provided in all rooms.
You might consider DLH. The same official limit of 5, but many rooms have 2 queens and a daybed (chair folds out to a single bed). DLH rooms are much larger, and will likely be much more comfortable for your family.
