i had investigated a few places several months ago.  basically, if it's in a tourist town like seaside or point pleasant, then they don't want to hear anything about meetings until september/october.  they are too busy fleecing the bennies to even think about our paltry sums of cash.
i have prices for a certain place in philly on the water.  some call it an amusement park for adults... i dunno.  they tend to be fairly expensive, to the tune of like $40 per person and the bar is your own business.  we wouldn't be looking at the cars too much, either.  if it's an idea you want to investigate futher, i could call my contact and find out what kind of specials and/or themes they are running now, and also an updated price list (can't imagine it getting any cheaper...).
