Sounds like it was really a good thing you got the wheelchair service. i remember one time in Miami, returning home from SXM, I basically almost collapsed in line, waiting for immigration. One of the workers saw my distress and pulled me out of line and since then, wheelchair for me.

That doesn't make sense, that they got you off the plane, only to stand on the tarmac, waiting for a bus. It would be interesting to hear how long it took people without wheelchair service, to get out of the airport. At least that part is over and you can enjoy! (Except for the timeshare BS, but that seems like self-inflicted to me.. Ducking..... )
