Some credit card companies such as the AmEx Plat card have been known to call hotels in emergencies to arrange for room, F&B, etc. charges to be authorized for the card account in the absence of a physical card.
They can usually send you a new card overnight without it being a big deal, although of course you need a hotel or some other address that receive the card.
Once my card was compromised (not my fault) and this was discovered the afternoon before I was leaving for a major international trip. My new card was delivered by noon the next day, just as I was leaving for the airport. They made it work.
