When I went to HH for the first time this summer with the camp I work for, the kids had a blast in the lazy river. I think because it was so light restriction wise, like them letting you go without a tube. All of us got tired wating for tubes, so we were just kind of lazily floating down the river, grabbing tubes that people would eventually abandon. Then races started, on foot, swimming, or on tube. The life guards didn't mind at all, and actually told me to tell my boss that my kids were well behaved and that they were the best group they've seen all day. After running maybe 5 laps in that river, I unnoficially re-named it the "un-lazy river".
