Jonny - I would suggest that you post some info about yourself, your riding experience, bike rental plans, and what loops you want to ride. That will make it easier to hook up with riding partners.
There are lots of bikers that come to the area during that time. But they range from round-the-world travelers to beginners on rented scooters. All of them have their own idea of what motorcycling is. You should try to find a riding partner whose plans match your own.
