Greetings! I did a little research and couldn't find anything indicating that this was still the case. That said, it WOULD make sense, as I can't imagine a lot of people - especially this time of year - being overly anxious to go on a ride which leaves you pretty much soaked from head to toe, and then spend the day wandering around wet. It may not be freezing in November/December, but it can be chilly. (Actually, I've always tried to save this ride for late in the day, just so I don't squish when I walk!)
