Look what I found on Allears.net a much better source than my brain lol...
What can I expect at check-in?
Check-in at FW is essentially the same as at other Disney resorts. If you're staying in a Wilderness Cabin, park at the Reception Outpost and check in at the front desk. If you're checking in early, you may store your baggage in the secure storage area behind the front desk. Here you will receive a your Magic Bands, and a portfolio containing park maps, an information sheet with park hours, and a Fort activities sheet. If you would like charging privileges on your Magic Bands and/or you would like to use express checkout, you can do so by providing the Cast Member (CM) a credit card at this time.
If you are driving your own vehicle or rental, you will then be given directions to your Cabin. If you do not have a vehicle, you will be driven to your Cabin via an electric cart.
Guests in recreational vehicles and those planning to tent camp remain in their vehicles and register at one of several drive-through windows at the Reception Outpost. Be aware that if you are arriving late in the evening, the drive-through lanes could be closed and you will check-in at the Reception Outpost.
If you are checking into a campsite and your site is not ready, you will be asked to park in the lot by the old Fort Wilderness kennel. You'll be given a phone number to call to find out when your site is ready. You can either stay there with your vehicle or you can go enjoy the parks and move into your site when you return.
