Hi, we live in Massachusetts, my 2 sons will be 5 and 7 next year. Is legoland, and surrounding area worth flying across country for a vacation? We did Disneyworld last November and of course it was fabulous but would love for the kids to travel some place new. If we were to come out, do you recommend Feb vacation or April vacation, what else should we consider bundling into the trip, how many days at legoland (btw my kids LOVE legos), how many days for total area. Just formulating ideas at this point. Thanks for any advice you can provide.
