I started out aiming for 4* in Boston, i.e. A-Cambridge/Brookline, B-Copley, C-Downtown, using D-Medford/Somerville and E-South Boston as rebid zones. I tried the following combinations at $40,45,50,55,60,65,70,75,80,85 and was rejected on every attempt with no attempt being detected as a previous bid A AB AC AD AE B BD BE C CD CE ABD ABE BCD BCE BCDE ABCD ABCE ABCDE I then tried for 4* in Metro-West, aiming for Newton-Waltham, and using the other 3 as rebids, and I tried $40, 45, 50 ,55, 60, 65 and got rejected Went back to Boston proper and tried for 3*s going from 60, 65, 70, 75 and was rejected on all attempts. I then started a new bid and aimed for $70 w/just Newton-Waltham and was finally accepted. Felt very relieved because I was afraid I was not going to have a place to stay Thursday night. I have 30 emails from priceline within the span of 1hr - average 2 minutes / request. :)
