We will be at Disney next week and have decided to pop over to US on our last day. Since we only have time for one park which park would you recommend? I wish we could do 2 days but we are staying OP at Disney and our tickets are included. We have Children 3, 5, 8, 9, 11, 15 (only 3 of them are mine) and 5 Adults. Thanks for any advice.
