You can watch it at
www.cbs.com, click on videos, daytime, price is right. Its about 11 mins into the show:
Included in the $4520 is
Airfare for 2 from LA to Knoxville
Rental Car
4 nights in a hotel
breakfast and lunch all days
Tickets to the park for 3 days
2 tickets for the human inflatable hamster ball thing
still seems expensive to me
