I wouldn't, and I won't loan mine out. I am very particular about how mine are treated, particularly washing. (Even Corelle gets old looking if granular dishwashing detergent is used in the dishwasher. There was a vast difference between the Correlle I gave my daughter when we closed out the summer place and her dishes.) Also, I would worry endlessly about my ruining someone else's dishes. If you do it, however, I love the marking ideas given above!
When we host 35 people, I only make sure that each table has matching dishware, flatware, and water glasses. Guests choose their seats, take that plate, go through the buffet, and return to that seat. Rolls, butter, salt, pepper and cranberry sauce are already on each table. If all are sitting at the same table, you might as well go ahead and expand your own set if it isn't a burden right now. As excited as you sound, you'll probably need them many times in the future.
Enjoy, whatever you do.
