Looking for suggestions of where to go for spring break.

My wife and I have a 3 year old and a 1.5 year old. We have some airline miles that are about to expire, so we're looking to fly somewhere. We took a week off in the beginning of April. I've always wanted to go to a national park, but am concerned they're too young for any of the activities. She wants to go somewhere warm, but is willing to compromise. For reference, we're in New England.I've started researching and it seems like most of the national parks won't be any warmer than home (50's at best), and a lot of them still have snow / certain parts of the park are still closed this time of year.We're not interested in all-inclusive resorts or theme parks or anything. We're more looking for something nature-y, but it doesn't necessarily have to be a national park.Has anyone gone somewhere this time of year where you (ideally) don't need to bring coats, and there's still scenery to take in and stuff for the kids to do? via /r/Parenting http://ift.tt/2F2e5dI
