That's exactly what turned us off on MIA. Last time we connected there, many elderly or infirm were really struggling with that long haul from the gate and with no assistance in sight. Not just on the airport IMHO..the airlines, cruise lines etc. are well aware of the situation and could work with the airport on a plan for when the Skytrain is down as often as it is.
