Do it. We had this offer last year (SIL owns at Grande Vista) and we took advantage of this low rate. Worth every penny. Worth every minute of the 90 minutes. We got a 2 bedroom, 2 bath ultimately-situated unit and it was the best accommodation we've stayed in in the Disney area. I can't say enough about it. I was scared to death by the reported ferocity of the timeshare presentations in the Orlando area. Did not have one scap of trouble from the Marriott "show". Low-key, nice, pleasant, rode to the demo in a golfcart and it was completely fine. I am a self-proclaimed non-confrontational "wuss" who was perfectly at ease. My enthusiastic advise is: GO FOR IT!
