Details
They've got all kinds of fun stuff here, there's plenty of space, and folks can just kinda roll in and roll out whenever they want.
EDIT: I guess now that it's official, I'll add on to this! :p Their website is http://www.golfland.com/anaheim/ if anyone needs more info. They don't allow outside food, but if anyone doesn't want to eat there there's a Carl's Jr a couple blocks away, and probably other things as well. There are 5 mini-golf courses and inside there are lots of picnic bench-style tables for eating, relaxing, probably even drawing and gaming (though, I don't know if they'll allow card/board games or not).
2nd EDIT: I hear now we're slated for rain? Does this upset anyone enough to not attend?
