Couldn't you hitch a ride with any of your friends from College to some of the Universities they're visiting. Although they might not be interested in the same Institutions, the ambience will be similar at, for example Northern Cities such as Leeds, Sheffield, Manchester, etc. This would give you some idea of the sort of Institute you want to attend, so say a City, or a small Campus University, or London or such other type of University.
I'm sure if you explained to them, they would be happy for you to go with them - and offer to buy them Lunch or something - as they're going anyway, but it's something to show your gratitude.
