I could be wrong but I think they are in a first come first serve basis. In some trips, they turned around my CPS repair on the same day and others I had to wait 3 days while standard turnaround is 6-7 days or so. Feel free to give them a call but you may have to wait in line based on prior orders received.
Thanks, If I decide to do it I'll give them and call and check out what they have to say on their time frames before I drive down there. Given the 5d3 is newly released I'm guessing they are going to be busy.
Which location did you go to? Or did you ship your gear to them?
I've just seen a link to a simpler looking procedure for trying the Micro Adjustment process on the post below... I'll probably give that a try before I go and spend somebody at Canons time on it...
