While we were visiting my cousins in Dallas for her wedding, we decided to take the kids to Legoland. It starts off in a rollercoaster style ride. Then you can go into different themes... We collect giraffes for my oldest, so it was a treat for him to sit on it.
They have a ton of activities to do and all ages can play. Legoland in Texas was a great adventure for the kids for behaving during the wedding.
