I don’t currently drive since I live in NYC, but I feel that unless the facility is rather cramped or has some other oddity that most people wouldn’t be accustomed to, I think valet parking is unnecessary. Usually it takes longer and incurs an extra fee in the form of a tip and I always feel a little uneasy about letting someone else drive my car. Last year I went to a KBBQ restaurant in Los Angeles that required valet parking. It was by no means a fancy restaurant and just had a slightly smaller parking lot. It felt so silly to have a valet park my friend’s car in a spot that any rather average driver could manage.
