There's going to be plenty of entertainment for everyone staying at the lock-in and there's plenty to do around town for those of you who aren't (and for Saturday night).
MOSI right across the street is running discounts for attendees and their families and is having a few special showings of The Dark Knight in IMAX. Cehck out

And definitely don't forget Howl-O-Scream at Busch Gardens.
