How was your room the last time you stayed in a national park lodging?/Kurt Repanshek file

Across the National Park System you'll encounter a variety of concessionaires, but there are four main companies that manage lodgings and restaurants. How do they rate in your eyes?

Unless you're a frequent, or even constant, park traveler, it can be hard to get an accurate impression of concession operations. Conditions can change from location to location, year to year, month to month, and perhaps even day to day. That understood, how would you rate the concessions operations in terms of cleanliness of your room, upkeep of lodging, service and meals in restaurants, staff helpfulness, and, of course, value?

Here are the major concessions companies and the parks they operate in:
