New Private Sale Site for Travel - New as of March 2, 2012
TravelTipping (www.traveltipping.com) has a simple email-only registration, so it’s vaguely private, and they don't seem to email too much, but it's early days. Prices “up to 75% off” hotels, resorts, villas, tours and cruises - this is not a room-night-only service but sells multi-day vacations.
TravelTipping has kind of a funny cow logo and alliteration in the name, but I’m not sure how cow tipping has anything to do with travel deals. A bit of a stretch if you ask me.
The site enables you to select regions rather than showing you a list of everything, and has limited availability for hotel stays which have a set # of nights. The packages are available until they sell out, rather than being on sale for a fixed period of time.
You can select the check-in date, but the length of stay is fixed. Looks like there are 10-30 packages available for any one hotel, so if there’s enough volume, deals will sell out.
