How long ago did you request them? I would call DME on Monday and ask for more to be sent out. They don't need a ton of time to get them to you. Worst case scenario is that you just give the DME CMs the baggage claim receipt and they will go get it from the baggage carousel upon arrival, and then deliver it to the resort.
I believe DME tells us that they need 10 days lead time to process and mail out the DME packets....not sure if addtl tags fall into this catagory as well.
