We have not been to US or IOA before, really not interested because children were not tall enough to ride most of the rides there so always stuck to Disney. This year they are 7 (boy) and 9 (girl) and we are considering going on this vacation (beginning of April). Problem is, with Disney parks too and visiting family, we would only have one day to do both parks. Is this feasible? Long days don't bother us, we usually get to MK at opening and leave after fireworks. If I am paying to go I feel like I need to get my money's worth! Any response would be great.
