If you paid this years MF already and have not used it is going to be a crap shoot. IF you sign the letter you get a price for the week locked in AND as a hotel you don't have to prepay, PAY at the end of the week on leaving ( so you have some leverage on service) IF they want you to pay in advance, I'd say no.
My guess is from now till the first of the year will be a transition period to hotel ( which will be late in the high season for booking a room so might see some deals).
SXM??? Wendell
