There will be overflow parking to the right when you come into the park-- look for our signs (but its 5 dollars a day and limited, so try to carpool!)
You can use VRBO.com, Airbnb.com, and Homeaway.com to find a house/apartment to stay in. There are many options available in Cape Charles (which is a 15 minute drive away). Uber does operate in the area (although may be limited). You can also camp (and be walking distance!) or rent an RV. The Kiptopeke Inn also has availability.
We will have markers of areas that you can drink. You're in the south, now... so there are weird laws here. Don't drink outside these perimeters because there is a cop on duty to make sure you don't.... yep. Drink as much as you want, but please don't drive. Welcome to Virginia! :)
