We just stayed there earlier this month and they have their own check in area. When we went through the gate to enter the grounds I guess they must notify the resort because when we pulled up and I got out to check in someone came up to me and welcomed me and already knew my name and walked me right to the check in desk. So you won't get lost at all. They show you where to go to check in.
Enjoy your stay. We absolutely LOVED our 2 bedroom villa (we had a dedicated 2 bedroom with two queen beds). I think these are the nicest rooms so far that we have stayed in for
DVC.
