If they are people who work in hotels and performing services like this is a part of their job you can call them "hotel valet".

I have to say that I have never come across rider when driver or passenger would be the accepted and common usage to cover a car. However, your question is interesting as I consider it perfectly correct to say, "He [neighbour] gave me a ride to work in his new car". To my way of thinking I remain a passenger in my neighbour's car and not a rider in this situation or context. . I wonder if we have a clash of American English versus British English here? In the UK it is common to ask someone if they would like a lift to work and this would be readily understood whether the mode of transport is a car or a motorcycle. However, I don't think lift would be understood in American English in this context whereas ride to work would be. But then the situation becomes even more complicated because we talk about a pillion passenger (BE) in the context of a person who sits behind the rider (the person in control) of a motorcycle.

Pillion passenger: A pillion is a mostly British English term for a...seat behind the main seat...[of a] motorcycle...A passenger (my emphasis) in this seat is said to "ride pillion"... (Wikipedia)
