We went on Monday and Tuesday and had a great time. We are even talking about going again.Next time it will be for more than two days. DD loved the museum and couldn't get enough of the Barbie exhibit. We stayed at the Crowne Plaza- Union Station in one of the train car rooms. Great if you have kids who like trains.
Re: Thanks for the review on the Indy Zoo and Children's Museum
Glad you had fun! And thanks for the info on the hotel...I never knew that. Not like we need a place to stay here, but that would be fun for DS to stay overnight. I bet he'd love it.
