Stayed at Cherry Hill last year, during my kid's spring break.
Nice park, full amenities. It can be a bit load, it is beside an interstate (I'm in a Hybrid), but nothing too bad.
Easy access to the Metro, either via bus that stops at the gate, or drive two miles to the metro station, we did this based upon the park staff suggestions. You can also purchase Metro passes.
We stayed at Cherry Hill Park, College Park ,MD in April. There are tours right from the campground and buses to the metro. You can also purchase your metro tickets right at the campground.
Your best bet for your first visit to DC is Cherry Hill RV Park in College Park, MD. It is the closest park to DC (there are no parks in DC). It is a little more expensive then some other parks that some will suggest, but pay the monies. Its worth it.
The park is clean, the staff is user friendly and you are only are a short bus ride away fro the METRO. The bus stops at the fron gate of the campground and takes you the the CollegePark Station. Or if you chose you can drive overt to the Greenbelt Station and catch it there.
The METRO is user friendly. You can preplan your trip here.. Or you can just talk to the Cherry Hill staff and they will help you.
I work across the street from Cherry Hill and I ride the METRO downtown to headquarters office all the time. PM me with any questions.

Thans much folks. Sounds as if Cherry Hill is the place to go. From there we will go on to Acadia NP in Maine. Any suggestions for Acadia area. We will have a scooter and two bicycles.
Pohick Bay Regional Park has a nice rustic CG with water/elect sites, but no sewer. Lot cheaper than Cherry Hill, and a short drive from the park to the closest metro station.

Go with Cherry Hill. If I read correctly, you have a scooter and two bikes. I would not suggest riding those to the nearest metro station anywhere in the DC area.
As for Acadia, we like Bar Harbor Campground, but, last time we were there they were still not taking credit cards. It is on the local trolley/bus route however. I would suggest that the National Park Campgrounds inside Acadia (No hookups) would be great, but I would be surprised if you could get a spot.
Travel safe and have a great trip.
