Definitely, you might be able to get a cot in there (I think it's $15 a night extra?) and then there is room for all 5 of you. The room is 356 square feet with 2 beds I believe, compared to the 269 square feet per side (538 square feet total) for the kids suite, so you are getting 66% of the kids suite, plus, with no extra bathroom, it would be more spacious than 66% of the kids suite. There is still a fridge and microwave, in room safe, Keurig coffee, etc. Did you check to see if the Queen suite or King suite is still available? They have one of each, and those could also work, but they would be more pricey. Another option might be getting two rooms with adjoining doors, BUT they can not guarantee it, for example, if a customer checks out and leaves the room in poor condition that needs extra work, you may not be able to have adjoining rooms. That's what I love about the kids suite, but I do understand it's not available for your dates.
I just read about Caleb, in the wish trip report - what a wonderful and strong child he is!!

I can tell how blessed you feel to have the family you have. It is a miracle, these people who come to us who are different, or who have special needs, but who fight so hard to manage life on a day to day basis and to be so happy. Blessings to you and your family.
