I've been up and down the Marriott chain (including emails to Arne Sorenson and other executives), a phone call with a hotel exec and Marriott executive customer service to try to get a satisfactory compromise. I haven't received that. Instead I have received a range of price offers none of which I think are good enough. Now trying to decide on next steps. The BBB of South Florida is one forum as is taking them to court, though that might not be worth the effort.
