I went and checked the little box on my ticket that said I wanted wheelchair assistance, and so I got it, no fuss. The lovely little Somali woman who took me through ticketing and security was fairly adamant that markgritter and timprov must be brothers, but this is a minor inconvenience. Checking the box in advance FTW. Because, seriously, folks, it was hard enough to deal with turbulence, takeoff, landing, the little train dealie to the rental car, etc., without having to haul my butt through airports pulling someone's arm out of his socket. Round and round and round. Uff da.
But the hotel is good, and soon there will be Cuban food, so there's that.
