When I travel with my parents, the accommodation absolutely must have a window. Just finding that can be really tough, and it's usually not cheap. Food is generally less of a problem; you can often find group deals in most cities. For getting around, Didi (ride-hailing) is definitely my preferred choice. Speaking of taxis, the requirements for drivers have actually been lowered. Now, you just need a Beijing residence permit or ID to be a driver, unlike the old days when you had to have a Beijing hukou (household registration).
