I agree with this. AND if they are Harry Potter fans, they just opened up that new Harry Potter theme park as part of Disney. Non-stop stuff to do around there. http://www.universalorlando.com/harrypotter/ I think the Grand Canyon is nice, but it might be a bit boring for kids. It's like once you've seen it, you've seen it, and you're begging dad to leave. Hawaii might be fun though. Orlando might be a bit hectic and not seem like a relaxing vacation to YOU exactly, but your kids will have so much fun. You will enjoy making all of those memories and seeing them have the time of their life.
