Always use the yellow tags so we don't have to touch them until we unpack them. This next trip we can't do that as we'll be spending the night at the airport Hyatt before heading over to YC the next day (got a cheap flight on a Sunday evening and a free room at the hotel from points).
Thanks for the information on picture posting. We'll have to try it one of these days.
The Hyatt does provide a service where they will pick up your luggage from the carousel for you (and, I believe, deliver it to DME the next morning). I'm not totally sure how it works (or what it costs), but you may want to look into it.
