This is the recently developed sister site to LuxuryLink.com.
It never held much interest for me since we hardly travel with the young'uns.
They have promotions for % off and first-time discounts tho, and some pretty nice specials all over the world, but mainly US and popular vacation destinations.
They have had some "mystery" auctions that went for less than 10% of the retail value (about 20-25% of the usual auction price) You can find the property name w/out too much digging around by destination and if you're flexible (some are widespread dates/availability) you can get serious DEALS--better than many interline ones.
If this violates the site rules, bet you can get familygetaway to buy advert on here...
I've bid on several pkgs but my bids$ were lowball, so I wasn't overly expectant of winning most of them. The regular deals/auctions are well-priced tho, so check them out.
