I took my 24 month old and 9 month old to the wilderness. They both loved it. We used the outside area a lot. One of the indoor rooms was really noisey and my 24 month old freaked out a bit. She didn't like loud noise then. There was definately plenty of things to do, and kids eat free! Your 2 year old might be jealous of the 5 year old, if he isn't able to do all the same things.
Anyway, overall my kids loved the wilderness. We had so much fun, we stayed an extra day.
Have a great trip.
