We did this once when we were younger (and poorer) at the Westin in the Palm Springs area. Got a free weekend and free meal vouchers. The idea was that Westins would become a time share and could be used at any Westin around the country. I just kept saying "I like to go to (fill in the blank) “Yellowstone National Park”, “Is there a Westin there”. Of course I knew the answer was going to be no to every place I mentioned. I had the guy flummoxed. We did our 90 minutes and left.
