Stop everything! Disney announced that this Fall they will turn every Disney Cruise Line ship into Halloween On The High Seas!
While you may think this is geared towards kids (which it actually is), I think every 20-something will definitely want to be a part of this ghoulish time.
Disney is known for their "Mickey's Not-So-Scary-Halloween" and it continues onto their cruise lines come this Fall.
