My husband is Potowatomi Indian and their reservation is in Wisconsin. A few years ago, they built a casino and lodge there and all tribal members submitted names for the different restaurants, lounges, etc. All of the names of the tribal members who had their names chosen for the rooms had their names put in a hat and drawn to win an all expense paid trip for 4 to WDW. I think they drew 4 names... and my sister in law won. She took her brother (my brother in law) and his daughter. She didn't have a 4th person, so they gave her something else in leiu of the 4th plane ticket and park ticket.
She won airfare, 4 nights at the CBR for 4 with UMPs for the corresponding days, and a free lunch at Planet Hollywood.
My DH, DD and I met them down there. They seemed to have a great time... we didn't really hang out with them too much, though.
