Looking for suggestions at places to camp in Yellowstone National Park. We are traveling via Prius and are looking to camp grounds in late May. I know the parks tons a bears and wanted to know about leaving cooler of food in the car during night bad thing? Bear boxes at campground? : camping

Can anyone recommend places to stay in the park? I haven’t made any reservations and I know since this last minute trip they are booked up. I assuming they have 1st come 1st serve spots? We plan to camp during the week so it should be a little easier. If we can RSVP now which places in the park do people recommend? We have never been to Yellowstone.
