1) the time it takes vary on when you leave and what's going on.
leave the parks before both close and its less then 10 minutes
after Park closing 20-30 minutes
after Mardi Gras concert almost an hour
2) you pay when you pick up the car, only one window takes CC, and unless it's really crowded, it is only the one open, if they open the 2nd window its Cash only
3) directions to valet parking would depend on where you are coming from
if coming from Turkey Lake, instead of going straght at the light that lead into the parking structure, make a left, then make a left at the next light
if coming from I4, stay in the left lane, once you pass the general parking stoplight it will be the first one on your left.
there is a 3rd direction, that you would make a right but have never driven that way.
