Personally, I would use 2 free days and make sure I've found the best discounted contract ID and any other possible coupon codes from the sticky in this forum.

As far as getting your credits back for cancelling the reservation, it depends on when they're set to expire. As mentioned above, if the credits were to expire on 12/31/2010, then you won't get them back. If they're expiring on 12/31/2011, you will get them back. The 1-2-Free credits expire on 6/25/2011.
