The sales usually last about a week then new properties and destinations become available, I am always checking to see what is coming up. Currently I am on the hunt for a fun get away to someplace close to us, although there is a beautiful hotel called The Garden Gables Inn (again, this goes to the B&B site, not Sniqueaway) coming up in Lenox. MA that is a Bed & Breakfast Spa that would be a great stop for us when we visit my Nephew. A nice feature of the site is being able to set up reminders for future deals, but if you are not interested in what is currently on sale be sure to sign up for the emails, then you won't miss a fantastic deal.
As far as travel deals go, I have not seen any other site that has been able to provide this kind of discount on such nice properties. I know you can name your own deal and get discounts with some of those other sites, but you may end up in the smallest room they have since you don't get to see the room in advance. When I found Sniqueaway I was overjoyed, and even though I haven't booked anything yet, I love to look at the new sales and take a mini vacation from my sofa.
Have a great weekend everyone!
