Can someone answer this ridiculous question for me?

I hate to ask this question but I will anyway.  I've been using the same carabiner keychain for a LONG time.  It looks kind of beat up, it's unwieldy, and it's heavy.  I'm one to use things indefinitely if they don't need  replacing.  However, it was becoming unmanageable.  

My question is, which end of a valet keychain does the valet get-the actual keychain part, or the silver ring part (not that I'm in valet situations often)?

Obviously, he/she will get the end with the car key on it but which end should that be-silver ring or keychain?

Again, pardon my ignorance but I reasoned that the valet gets the keychain part because often, it has the car logo on it, which may help ID and find the car.  More simply, the car key goes with the car keychain.  Is there a right answer or is it personal preference?

Or, do I simply detach the key from the keychain altogether, and just hand the valet the key, sans any attachments?

I've never been in that situation, but I would give JUST my car key, nothing else. You might want it on it's own key chain if you need one, or make sure it is detachable. Make sure you take your garage door opener too, here they are with your address (on your registration in the car) and it's very easy for them to open it up and get the 'sequence' to install in a garage door replacement device. You have me curious now if there is a right or wrong way.

We have only given the key fob and the car key, which we put on a separate key chain for that purpose. They need the fob to get into the car and the key to start it to bring it to us.

My car only has a fob. So, which end would you put that on, if you only want to have the one valet keychain?

I don't know if this is the "proper" way, but I would give the valet only the ring.

Well, it seems that is one of those questions for which there is no definitive answer. At least, I haven't found one.  I finally decided that if I were to take my house keys off and leave them behind, for whatever reason, at home or in the car because they're too cumbersome, I'd want to have my car key attached to the keychain, rather than just the little ring.  However, I don't think I'd want to leave the keychain with the valet. Fortunately, I don't do much valet parking.
