dirtgirl wrote So do we know where the valets park the cars?
The valets are supposed to park at Giant Eagle. I know this because last summer I called Basi about 10 times to let them know that the valets were parking on Neil, Buttles, and Hubbard. Repeatedly. Even after my neighbors and I asked them politely (at first) and not-so-politely (the umpteenth time) not to park on the neighborhood streets. When I called the Basi managers were very apologetic and said that they pay for spaces in the Giant Eagle parking lot and the valets should be parking there. The valet company that they hire was crappy about laying down the law with the valets, though.
Notably, this year I have seen the valets running to and fro the Giant Eagle parking lot rather than the 'hood. (I have also noticed that this year I am able to find a parking spot on my street between the hours of 5 and 10 pm.)
Also notably, you can park at Giant Eagle and not get towed as long as it's not Comfest weekend. I have had friends park there for literally a week while they went out of town and their car wasn't touched. FYI if you don't have cash/ don't mind walking a block.
