I've just arrived in Las Vegas for the C++ Connections conference.  I was lucky enough to find myself on one of those almost empty flights that are so rare these days, but Great Arbiter of Travel Fortune made sure I paid back that bit of good luck, with interest.  When I arrived at the hotel and tried to check in, I learned that my reservation had been lost.  Extra lost.  They didn't even have a record of me in their computer system.  I was a non-person.  After cracking open my laptop at the check-in counter and providing a few extra details, they were finally able to discern that the reservation that used to be mine somehow got cancelled and evaporated from the system.  Convinced that I wasn't some bozo trying to check in without a reservation, they did find a room for me in an otherwise full house, so all's well that ends well, I suppose.  I'm not sure what broke down in the reservation process, but props to the nice lady working the front desk at the Mandalay Bay who hung in there with me for like a half hour making sure I got a room.
