Some delegates may get money from their hall councils or their own pockets. Your group may decide to hold some fund raisers. Revenue sources need to be determined early because registration forms and money will be due several weeks before the conference. This question is closely related to how many people can go. Set a realistic budget for travel.
Many modes of transportation are available.
If your school or organization has access to vans or buses they are a good alternative. Larger delegations will often charter a bus or look into group rates for a train or plane. If your school can't fill a bus alone, contact other schools in your area. Be sure to get correct addresses and phone numbers for all delegates before they leave campus. In you delegation meetings during the semester you should decide where everyone is to meet or to be picked up on the way to the conference.
