Just finished checking out EV Rentals...they have hundreds of Last Minute deals at timeshare resorts around the country (and some outside of the country). Prices are great...$349 for 7 nights in a studio, $379 for 7 nights in a 1-bedroom and $399 for 7 nights in a 2+-bedroom. (plus taxes).
Best of all (for most people) is that there is NO timeshare sales presentation required. You will most assuredly be asked to take a timeshare presentation (and be bribed with money or tickets or some combination) but it is NOT a requirement.
Recent statistics clearly indicate that more and more people are staying at a timeshare before event thinking about buying one. Smart move!
