Is there an age, height or weight restriction???

There is definitely a height restriction, though I can't recall the exact measurement. Kids below that height can ride with an adult in a double cart, as long as they're above a certain fairly low age. All the rules are posted on a sign right outside the ticket window.

I've seen 10yos riding no problem. I think as long as someone can buckle up securely they're fine

I think there are. Good idea to check

I don't believe so
