You have correctly named the 5 free rebid zones when bidding 4 star in San Francisco. Regardless of their location within the SF area, they are free rebid zones solely because they don't offer 4 star bidding. If you're okay with winning a hotel in USE, USW, SOMA or Embarcadero, then I would select your order of preference first. For example, let's say your first choice would be to stay in USE, followed by SOMA, USW and then Embarcadero. In that scenario I would bid as follows: Bid 1 - USE Bid 2 - USE, free rebid zone #1 Bid 3 - USE, free rebid zone #2 Bid 4 - USE, free rebid zone #3 Bid 5 - USE, free rebid zone #4 Bid 6 - USE, free rebid zone #5 If you don't get an accepted bid to any of the above, then to back to the Priceline home page and do this next: Bid 1 - SOMA Bid 2 - SOMA, free rebid zone #1 Bid 3 - SOMA, free rebid zone #2 Bid 4 - SOMA, free rebid zone #3 Bid 5 - SOMA, free rebid zone #4 Bid 6 - SOMA, free rebid zone #5 So on and so forth.... Get the picture? Don't do that! You never want to add a zone with the same star level while increasing your bid amount simultaneously as that can cause an overbid. For example, if you start out with USE zone at $70, then add SOMA and bid $75, you never gave the SOMA zone a "chance" to score a room for $70. Give each 4 star zone the chance to score a room at your entry level bid price because you have no way to determine which zone has the lowest price. Good luck and keep us posted on your progress!
