Hello -- My husband, daughter (3.5 yo), parents-in-law and I will be in Orlando for eight days in August before we go on a RCI cruise. We are going to stay off site at a villa but we are planning four Disney days (one for each park), as well as a few down days with shopping and pool time at the villa.We have one extra day where we want to do another park but I am undecided as to which one! Here are the options we are considering: 1) Legoland -- just the park, or could we do the park and waterpark in one day? 2) Volcano Bay or another waterpark - which would you recommend as best for that age 3) SeaWorld Just wondering which you would recommend as the best option with a 3.5 year old? Anything we're missing that you think would be awesome for that age? Thanks!
