The UMass Alumni have a travel package here .
If you're willing to just fly and stay, you can do the trip for substantially less .
AAA's site is here . If you are willing to make a connection two people can fly round trip from Manchester, NH for as low as 395/person.
Travelocity's site also gives flight and motel packages about $400 less than the Alumni package.
If you are willing to give up direct flights, you can cut big $$$ off the cost of the trip.
UPDATE: We were told downtown Chatty is sold out. We were able to get reservations farther out. If you are thinking of going. Make a command decision and make your reservations. You can always cancel. Then work on your flight.
