Why I stressed "easy." Mocking up a new T-shirt when you create dozens each year or getting a few CMs out on a Thursday morning, that's relatively easy. Bringing buildings back up to code,(shouldn't be too difficult) retraining bartenders(good bartenders don't need retraining)/door hosts(such a difficult job)/managers(there's certainly no shortage of those around!), coming up with a marketing plan that doesn't make you look like complete idiots for closing PI in the first place...that's difficult(Now THAT"S a formidable task!). I think it would be profitable, but it's not an easy profit.
Sure, the first night they would. I'd even wager there would be lines the first month. But reality check: the AdvClub was never even the most popular venue on PI until its final week of existence. It only works in the context of a nightlife district, and that district needs to be kept fresh and exciting. I think it's well known I'm no Disney mark, but I do want to keep the discussion honest.
