I zoomed in on this in google maps - so you get in the right lane and go through the MK sign I assume? Then almost immediately a right onto Vista Boulevard? I won't have checked in yet and I am not an annual passholder, won't I get stopped at the gate?
Yes, your understanding of the directions are correct. And you'll get stopped, but just let them know you're checking in at Fort Wilderness. You won't have a problem!
