Donita Glitch operates DVU, Donita's Vacations Unlimited. She owned the company that Dial an Exchange bought out here in the US. She had a no compete clause for a few years and is finally getting back in the business.
I used her before she sold to DAE and while she was with them. She's very knowledgeable about the business and has been doing it for some time now. You get very personalized service with her.

VRI*ety is the exchange arm of Vacation Resorts International, or VRI. If you own at a resort managed by VRI you are a member with no charge. You can deposit your non VRI resorts with them also.

If you'd like to get a VRI property to start exchanging there, I have one in the TUGG classifieds for free . PM me for details if you're interested. Once you're a member you can deposit any of your weeks with them and use their "Hot Deals." You need to sign in to see the hot deals.
