You do realize that by picking Friday nights you will have larger crowds than on weeknights, right? (In that case, you left out Friday, Oct. 19th.) The week of the 12th is also Columbus Day week - with bigger crowds overall than other weeks.
OK - I see that the party is apparently on Thursday, Oct. 18th. (Gee - how do you know the dates this far ahead?) A better night than Friday, in my opinion.
