We’ve done the Polar Express in French Lick a few times. It’s a lot of fun for young kids. We went with a group of 13, kids ranging from 4-9 & I was good for all. I’d recommend getting the upgraded seats in the dining & bar cars, definitely worth it….I'm interested to hear your feedback. We would probably be about 2 years away from possibly doing that... kids will be 9 and 6 by then.
