I've been to the Green Door a few times.  I was recently turned on to the Power Exchange and found it to have a better vibe all-around (for what I was looking for):  over 10,000 square feet of play rooms, dungeons, a dance floor, lotsa' movies (porn!!).  Lots of patient participants helping the "new girl" (me!) find her way around.

Perhaps the two of you could make a night of it and hit the Green Door and Power Exchange, then give us your personal feedback?  

Have fun and play safely!
