I've had days where I've been on 6 rides in the day and still enjoyed it, and it's because of the people I was with. I could have been by myself, ridden 50 rides in the day but I doubt I'll have enjoyed it as much. Once you've ridden all the rides a million times anyway you need good company otherwise I'd just want to leave after a couple of hours. So there's a way to enjoy it, with people.
