I was trying to find my post about the Houston experience, but since the Search function is currently down....
Basically it was an easy test and all the SPs were friendly and cooperative. Although the "free meal" sucked, the proctors were friendly and answered questions thoughtfully. Make sure you stay at a hotel that offers a shuttle to the center because the actual building doesn't have huge hot pink bubble letters screaming "STEP 2 CS CENTER HERE". It looked like a damn bank. You'll see what I mean.
Wait until you see how long the hallway is that links all 24 patient rooms. Wowza
(If the search function returns soon, I'll post the link to my original post, since I can't remember most of the info that you're looking for)
