We went to La Ronde this past Sunday with Ethan and had a great time. This being his second time there he got over his initial fears of the rides and really enjoyed himself.
The secret is to go early as possible. For the first hour there was no lines at all.
When we went on the kiddie roller coaster (for the first time) we get to the drop and he lifts his arms in the air and screams. And to think I was worried that he might be scared.
