You are on Maui now, correct? Go to The Cannery Mall, which is the mall by Safeway in Lahaina. See Syed Sarmad or one of the brokers. Advantagevacation.com is their website. That is how you get your deeded week that you can use every year, and for a much better price. See Syed and buy yourselves something that will be worth next year what you pay today.
That timeshare for $30,000 from Westin direct will be worth 30% of what you paid (or less) as soon as you are past that rescission period.
I wouldn't buy anything from Westin direct right now with the website malfunctions that are happening, even if they offered me a deal that was as good as Syed can do.
