I'm planning to stay from Fri - Wed. From websites that show the price, I can see that Fri-Sat seems to be a popular weekend. Rather than bidding Fri-Wed, does it make any sense for Fri-Sat (bid a higher rate), then Sun-Wed (bid low). I.e. I'm wondering if bidding high for all the days OVERALL makes me pay more? Obviously the catch is that I'd have to switch rooms/hotels. Thoughts???
