That's a really tough one because both of the parks are so unique. When my DD was nearly 3, she enjoyed the waves of the wave pool at TL, but we felt the childrens area at BB was better. Another great thing about BB is the ski patrol area meant for kids a little older. My DD has been playing in that area since she was 6. Many people mention that BB doesn't have a lot of shade, but we've always had no problem finding a nice shady spot.
