SniqueAway a few months ago from George Hobica of Airfarewatchdog. SniqueAway, which is a part of the same company that owns TripAdvisor, is a member's only site offering short run sales at luxury resorts and 4 and 5 star hotels, mainly in North America and the Caribbean. The sales run about a week and the savings can be pretty significant. We were able to book a weekend at a four star hotel for what we were going to get at a nearby budget hotel for our upcoming trip to Florida. If you know you're going to be traveling and you are interested doing some comparison shopping it's worth getting the alerts. You can use this invite from me to sign up.
If you've already used it, let me know how it went.
