On the other hand ... seeing as how I was the dipshit who lost his phone at Anthrocon (and, I mean, a wallet isn't that much harder to lose), well, if you're prone to losing things, a card can be recovered, but cash is gone with the wind.
Or, additional tip, don't keep all your cash in the same place and/or with you at the same time (it's also just not a good idea to be hauling around shit-tons of cash all at once); and I'd say bring the card for emergencies (but maybe keep it in the hotel room stash instead of in your wallet).

Also, don't lose your phone. Just FYI.
