I've done a business trip there spring and fall for the last several years.
I called the lady at Camp on the Heart once, she was not real nice, not open yet, and not at all happy with the changes the oil fields were making in here town.
I stay at North Park Campground. Good sized gravel FHU sites, no trees. Mostly caters to oil field workers, and mostly permanent 5th wheel setups. Long waiting list. Bulldozing new sites as fast as they can move dirt and lay plumbing.
They do maintain a number of "transient sites" and they've always found room for me, even that first time when I showed up without a reservation.
This is not a destination campground. It's a place where oil field workers live.
Any kind of lodging in Dickinson is tough. People are renting out thier front lawns as campsites! All hotels are booked solid by the oil companies. Costs are through the roof. THey can't decide weather to go with it and build new stuff, or wait to make sure the Feds and environmentalists are not gonna pull the plug.
