This is my 6th day of not being successful using Priceline (this never happens). As of last night, I have made 32 offers since 9/6. I started on 4* hotels with a max of $96. The last two days, I have been including 3* hotels, with a max of $81, but making fewer bids due to the fact that it is harder to do free re-bids (there are only a few areas with 4* hotels, but a lot more areas around Philly have 3* hotels -- we want to stay somewhere in center-city) From my research on some of the hotel sites for downtown hotels, the room prices are a lot cheaper this weekend (Sept. 14-16) , but higher for the next two weekends (Sept 21-23 & 28-30). As an example, the Hyatt Penn is $129 this weekend, and $229 the next two weekends. This makes sense to me: I am guessing occupancy rates are a little low for this weekend and they are trying to fill rooms. Is there some kind of big event going on over Sept 21-22 that would suggest that hotel occupancy rates are higher than normal? Where does one check for such information? I will try again tonight.
