The first venue visited is Wunderbar Haunted Mansion. There is a HUD you must wear (but if you don't get it at the landing point, it will keep nagging you about it and offering) for the full effect. The HUD is just a small label in the corner that keeps track of the "exhibits" for you in seconds and you can use it to opt out.

The house interacts with you, giving instructions and hints. The experience seems to be non-linear, or maybe we were doing it wrong. Anyway, you have to find your way out of some rooms and work your way through the house. Once you figure out some part, you might have to do a room over again to move ahead. Click on everything clickable - no, go ahead (hrr hrr hrrr!). Some areas have to be experienced by one avatar at a time, but for the most part you can run through it as a group.
