Bachelor/Bachelorette Party

It looks like NYC is winning the poll for bachelor/ bachelorette party. I know I shouldn't plan my own party, but I do have an idea. we can get a limo (14 passenger limo van) for 12 hours. cost is $599 plus tax/tip and go to NYC. because it is a combined party we should definately have 14 people. the cost if we all split it is 46 bucks a person ( assuming with tax and tip the total is $650 bucks). If we leave Pa at 6:30pm get to NYC around 8:30-9pm we can party all night and return home no later than 6:30am the next morning. let me know what ya think so I can book it. I would like to do this in May
