Nope. You only get FOTL for during the day at the park. You have to purchase the HHN Express Pass for the houses. I wish it was different though.
Depending on when you're coming, you might not even need it. We just got home tonight (Fri.) and did every house, and most multiple times, without FOTL. We could have stayed and done 'em even longer but our feet finally rebelled. It's not always like that, but between the economy and being the early season, it's a pretty sweet time for power housing.
That and the fact they had the passholder party tonight and seemed to have forgotten a lot of passholders have the FF pass...which wasn't originally included.Hmmmm, no wonder they included tonight for the Frequent Fear pass.
From what I'm hearing they tried out the FFP yesterday as a test and they may extend it to every Friday until the event is over. This way they can rake in $30+ dollars from food and merchandice. Yay for the crumbling economy!
