Dave, obviously, doesn't know everything.
Some of the smart tuggers (timeshare users group) would differ on his opinion. But, you've got to learn how to maximize the value of your timeshare. A lot of people bought resale and know how to make their timeshare work for them compared to paying cash rates for high end resorts/timeshares.
A lot of smart timesharers don't share their secrets on how they travel economically and stay at really great resorts for super prices. Like I say, Dave doesn't know everything.
I know somebody that bought a great timeshare for practically nothing resale. His maintenance fee is $350 a year. When he trades it through II, he gets a bonus week from Interval. So he gets two vacations out of that one week. Plus, he has access to II's great "Getaway" weeks - which includes some great Vacation Club properties (sometimes Marriotts come up) for way cheaper than renting.
Last year this is what he got for the money:
$350 - resort dues
$ 84 - II membership
$129 - trade fee through II
$299 - AC (bonus week) (used at Marriott Grande Vista two bedroom)
$ 95 - Extra fee for trading into DVC's Old Key West 1 Bedroom
Total $957.00
This got him 1 week at Disney's Old Key West in a 1 bedroom and a two bedroom at Marriott's Grande Vista (using the AC). That comes out to $478.50 per week. I'm sorry, but you can't do that paying cash.
Oh, and if he wants to, he could grab an Interval "Getaway" week later in the year and take another great vacation for probably $300 to $500 dollars at a top resort anywhere in the world.
Dave is stuck in the 70's when it comes to timesharing.
P.S. Some people who buy 2 bedroom lockouts actually get "3" vacations a year out of their one timeshare week. They lock it off - 1 one bedroom, a studio, and if it qualifies, a bonus week from II. That's three vacations out of one week.
