See the General Info page for the newly added Safety Advisory. There is info about: ticks, mosquitoes, insects, wild animals, safety info about the Hillsborough map and info about the railway crossing on the Wentworth training map.
We added information about staying at the UPEI residence on the accommodation page. There are currently double suites available in Andrew Hall for $116/night plus tax. The campus is embargoed (eg you can't go anywhere on campus prior to the race) except for the small corner of the campus where the residence buildings and associated parking is located.
