first thing I'd do is invest is some of disposable grilling sheets, so your
food doesn't have to touch that nasty park grill. Or even bring your own grate to put over the grill.
Next get some aluminum pans and foil. cook the dogs first and
put em in the pan, might want to add some melted butter and
beer and chopped onions to help flavor em...wrap tightly with
foil and set aside.
Cook the burgers and put them in another pan with some
beef broth or french onion soup (not a lot, just enough to
keep a moist environment. Foil tightly, then put both pans
on the grill to stay warm until it's eatin time. as you get room
for the dogs, put em on so they can warm up again.
