Children can ride with you on your tube. No height requirement. Not allowed to send 2 tubes holding on to each other.
No height requirements. But they must be able to go in their own tube. There are a few different sizes of tubes also.
I think the recommended height they told us was 36" but there was no requirement. The employe than told us they sent a 1-1/2 year old down last week alone but he was bundled in there so he would bounce out. I do remember them saying no double riders so they would have to go down alone.
