We took our kids to
Legoland when my youngest was 2.5 (back when 2 year olds still got free admission, which changed when they opened Peppa Pig Land and started charging for 2 year olds). Most of the Legoland rides outside Duplo land have a height/age restriction. She was able to ride some rides because she was 35 in, rode a couple more later in the year at 36 inches, and another one (Jr. driving school) at age 3. She was tall enough but too young for the joust (age 4 min.) I've never been to Peppa Pig Land, though. But Legoland was wonderful for my 5 year old.
