I am very glad that I can repeat it again and got $45 on this great hotel during weekdays!!! :) (well, hotel website is $140 ...) This time I tried different "detour" that last one since I kind of know the algorithm and availability: 1. Bid $33 on 3* at Somerset (to confirm that weekday it won't give me Somerset Marriott since hotel website rate is $189...), rejected as predicted. I did not choose 2.5* to start and bid $45, as Marriott will accept $45 as I hit the trapped last week. (why? I believe the PL bidding algorithm is to match highest star first, so if I bid $45 on 2.5*, it will start matching on highest 3* and hit Marriott, then as soon as that happened, it announces "upgrade" to 3* not even try to match 2.5* even Staybridge will accept that offer as well and I chose 2.5* as my first choice. I think this is a "bug" of PL algorithm, at least they assume their 3* is better than 2.5* (and NOT honor customer's preference when possible!!). Well, better or not depends on the situation. When I need free Internet to work remotely, I do not like Marriott charges me $6.99 (yes, increased from $4.99 recently). Besides, Marriott can not compete with complimentary breakfast and dinner. It's great lobby, ballroom ...etc that I have no use ... 2. Then I add 2.5* and bid $37 (just to test if another 2.5* hotel Courtyard will accept, but now I think this step does nothing but testing if Staybridge will accept $37 since Courtyard has $159 website rate and never accept $37 for bids for a long time ... It is rejected. 3. Then I add Lebanon and bid $39 (I think by now, it is confirm both the 2.5* Courtyard there and 3* Holiday Inn Select Clinton will not accept lower than $45; this seems to be true for most Courtyard during core weekdays ...) The steps is also redundant as a after fact thought. It is rejected. 4. Then I add Bridgewater and bid $42 (Bridgewater only has 3* Marriott that with min $47, so this is just a free bid trying to see if I can get Staybridge with lower than $45 price. Failed. So, it should be either $43, $44 or $45. 5. Then I add Edison Woodbridge and bid $45 (note: I did not add Edison - East Brunswick, or I may hit 2.5* Cleriaon Edison, min $35) This zone has 2.5* Courtyard and Hilton Garden Inn that both will not accept low bid during core weekdays, so I was safe and know I should get it, and yes, I got it!!! the Staybridge Suites. Review: If I were going to try again to get Staybridge, I guess I should just do this: 1. Bid 2.5* at Somerset - Piscataway zone on $33, or just anything low, to fool the PL algorithm and exhaust matching on this zone. 2. Then add Bridgewater zone and bid $45 (somehow PL will start matching on 2.5* at Bridgewater zone, which there is no such, then matching 2.5* on Somerset, kind of "stack" last in first out. Then will hit Staybridge right there!!! (if nothing available, then will come back to match 3* on both zone, then may hit Somerset Marriott) 2a. I may bid $43 to see if it is the minimum, and later select Edison - Woodbridge and check $44, but I believe $45 may be the min now since, otherwise, when $45 is more than 2.5* Staybridge will offer, it should keep going on to match 3*, then announce an upgrade. So this is not necessary but can be a bidding exercise... 2b. I even believe weekday Marriott has $45 min, and during weekdays, if one bid $45, one will get either one depends on the bidding sequence. Lemma 1: One can win a lower star level hotel with equal price than that of some higher star hotel in the same zone by first selecting the higher star hotel with a low bid to be rejected, then add the lower star level with higher price bid to be accept lower star hotel than the undesired higher ones. If this Lemma 1 can be proved and become a Theory 1, then one should be able to get this Staybridge Suite over Marriott by doing: 1. Bid 3* at very low price, say, $30 at Somerset - Piscataway (where Staybridge located with only 2.5* that has equal price to 3* Marriott), then it will rejected. 2. add 2.5* in the same zone and bid $45 to get Staybridge. Lemma 2: When PL matching hotel at same level, it starts with the hotel with HIGHEST minimum price. PL program has table of all minmum (i.e. PL pays hotel), and it is merely checking the "availability" of hotel following the preset order. If this Lemma 2 can be proven to be a Theory 2, then it explains why it is almost impossible to get nice 2.5* Staybridge Suites without "detour". e.g. during weekend, 3* Marriott $33, 2.5* Courtyard $37 and 2.5* Staybridge $45. If one bid $45 on 2.5*, since Lemma 1 says it starts matching on highest star, it will hit Marriott right away and announce an "upgrade". But if one bid $30 on 3* to be rejected first, then add 2.5* and bid on $45, one should be able to get it. But if one does not know $45 is the magic number and bid anywhere between $37 and $45, one will get Courtyard even with detour.
