Complimentary Tickets
As a favorite southeast Tennessee destination, we receive a high volume of donation requests each month. We are happy to consider a donation (4 general admission tickets) to other non-profit organizations when provided with the following details: 
Name of non-profit organization
Name of fundraising event
Date of fundraising event
Name/title of non-profit organization representative
Contact information for the representative
Mailing address

While we wish that we could grant all requests, as a non-profit organization we must limit the number of contributions we make annually.  Donations are limited to one-per-year and must be submitted 6 weeks in advance of your event, for approval and processing.
