As modes of transport have evolved, tourist lodging has adapted to serve each generation of traveller. A stagecoach made frequent stops at roadside coaching inns for water, food, and horses. A passenger train stopped only at designated stations in the city centre, around which were built grand railway hotels. Motorcar traffic on old-style two-lane highways might have paused at any camp, cabin court, or motel along the way, while freeway traffic was restricted to access from designated off-ramps to side roads which quickly become crowded with hotel chain operators.
