I've got the details for the Laser Quest thing.

If we just book the normal way, it would be quite expensive. For 1 hour would be about $22-23 each person.
If someone (just one person) who participates in this has his/her birthday in the month that we go for this laser quest thing (november, that is, probably), the cost can be $250 (in total) for 2hours with up to a maximum of 30 people (more people = pay less each).
If one person has a "HomeTeamNS" membership, the cost is lowered to $150 (which translates to about $15 each person) which is cheaper than the "normal (corporate) way" and its for 2 hours instead of 1 hour.
Another cell group (willow) seems to planning to go for some laser quest thing too.
Price can be cut by about half if we go together.
I'm not sure if we want to "play" other things there
Other things could be
Squash, Bowling, Archery (Archery needs membership, others I dont know), Air gun shooting (which is similar laser quest so...), swimming (the swimming pool is quite plain, and swimming boys and girls together...may not be a good thing...).
Yeap. Thats that and thats that.
