Having just arrived back home from a week at the GF, something you may want to consider:
In the GF there is a room type called the Outer Building Garden View Deluxe that is not available for booking, is available nonetheless, and gives you oodles of extra space.
For our family of 4, it was amazing. I learned about it on a
YouTube video, and when I checked in at the front desk asked the manager if he could move us from a theme park view to a courtyard view and give us this larger room. Not only did he grant my request but it came along with a savings of 100's of dollars per night.
The difference is another 10 feet of depth, the relocation of the sofabed, and the addition of a coffee table, more cabinet space for clothes, and second TV. If your kids are young it may not be that important, but having that extra area for our teens was amazing.
