I’ve written several times, though not lately, about using Club1 Hotels in the arsenal for finding a great hotel deal. Since they’re a ‘membership site’ (you can sign up for a free membership) they can show hotel rates that are cheaper than what you’ll find on a hotel’s own website, evading Best Rate Guarantees.
Club1 isn’t cheaper on every stay at first search, but readers have saved thousands even on a single stay. They do guarantee savings on every booking and offer price matching. But even better they’re offering 10% off their already-discounted pricing with promo code.
