I have just returned from my AFDA endorsed trip to the venue for the 2008 World Ultimate & Guts Championships.
Worlds will be hosted at the University of British Columbia in Vancouver, Canada. The university boasts some of the Vancouver's best attractions, including the Museum of Anthropology, the Chan Centre for the Performing Arts, and the UBC Botanical Garden and Centre for Plant Research.
I can confirm that field layout that is proposed in the bid document can be accommodated by the venue. There is adequate parking, and it is only a short walk to the accommodation.
Most important of all is the grass itself. The turf is low cut, even and lush, yet on a firm base. Prospective players at this tournament should definitely bring cleats. Coaches and support staff should wear footwear that can cope with some moisture yet has a good grip - you don't want to slip while walking to your team's timeout.
