Just an FYI about how DME handles luggage behind the scenes. Notice the lil barcodeon the tag? That barcode gets scanned no less than 5 times between the airport and the resort. Add to the equation GPS tracking on the delivery trucks, DME always knows where each bag is. So if the airline loses a bag, it wouldn't be scanned by DME, and they'd know instantly that it's an airline issue which can happen regardless of DME or not.
The good thing is that with this tracking system, DME greatly reduces the liklihood of actually misplacing a bag. And if it does get misplaced, they know where it is, and can often solve the problem before anyone realizes it.
