We stayed in a kidsuite in December and LOVED LOVED LOVED it.
Did I say we LOVED it? It is actually 2 rooms, we had a king room and the kids had the cutest room with a table and chairs. My kids were younger than yours (1, 3, & 5) but they really loved spending time in their own room. I think your kids will be fine as well. There are 2 twin beds in the kids area and really nice bathroom that can be accessed from either room. It is going to be really hard for us to go back to a regular room. But you may want to check on connecting rooms. Depending on the time of year with the e rate you can get 2 rooms for 250.00 and I know the suite is much more even whne discounted.
Good luck.
