Hello, here is the blurb from the email I received from Overland Expo:
Overland Experience registrants: Packages must be purchased before arrival. Registrants can check-in starting on Thursday between 1pm and 7pm. Please plan to arrive during daylight hours. When you arrive, park in the temporary parking lot across the RV park or in the open lot across the road from the Lodge. Proceed on foot to the Headquarters / Registration Check-in area. You will receive your badge, bag and other materials. Don't forget to bring your schedule of classes you signed up for.
Weekend Pass with Camping: Attendees can check-in starting on Thursday between 1pm and 7pm. If purchased before arrival, bring your receipt (emailed to you at time of purchase) and your ID to verify. Upon arrival / check-in, drive right to the Ticket booth for Day Passes and show your receipt to get materials, wrist bands. You will be given a camping pass and directed to the main campground, which is in an open field.
Because of the demand for camping and new infrastructure going in to improve the camping area (yes, we listened!), we are limiting camp access to Weekend Passes and Overland Experience packages only. Camping is allowed from Thursday – Sunday nights. All sites are on a first-come basis.
