You'll love it! It'll be a great exercise in courage for you just like it always is for me, and tons of fun!
I have a couple bits of advice for you as well, to keep you from getting too scared and thus lessen the likelihood of pants- wetting:
1) In Houses, always stay in the center of the path, DO NOT get too close to the walls on either side. Scareactors often hide in secret passages and hidden alcoves in the walls, known as "Boo- holes," and if you get too close to a wall where one of those is, then for the Scareactor inside it's like thrusting a steak in front of a starving man.
2) Also in Houses, be aware of your surroundings. They love using tactics like distraction (i.e. getting your attention to one spot with a Scareactor or special effect, so they can then nail you from behind with another Scareactor or effect) and camouflage (i.e. Dressing in special costumes to blend into the wall or decorations in order to then pop out at people) to nail unsuspecting visitors.
