ive done it. we didnt get a deal like that, but this was 12 years ago and we already had disney tickets.
we got free tickets to universal for doing it. it was much longer than 90 minutes though. we had to be out at the bus at 7 am. then it was a 20 minute ride to the timeshare. they agve a breakfast, but it was gross muffins. then we sat through a 90 minute presentation. then they had people that would take each couple and try to convince them this was a good deal. and they atlk to you forever, no matter how many times you say no. then finally they let you go back to the buss. as soon as everyone is dine either buying one or not, then you get brought back to your hotel. we were probably back around 10:30.
i would never do it again.
and and the hotel we were staying at, by the time we got back, the busses to the parks had already left, so we had to rent a car(although now, i rent a car everytime even if i stay in the park)
