If you have the time and want an INSANE haunt experience, go 34 minutes north. Seriously, we go everywhere for haunts, and it's the most interesting, interactive, funny, and fun haunt we've ever done, no question, hands down. (-- though we've never done BLACKOUT NYC to be fair)
The line gets HUGE so get there before opening.
If you have a group of 2, they will send in the two of you by yourselves. We've done it twice over the years.
Spend the extra $$$ for the blood experience. This is critical. Don't wear clothes you don't want to get ruined.
