Ah, the dreaded elevators. We specialize in cruises for people who are wheelchair users and slow walkers. In addition to unthinking adults (which runs rampid on many lines), there are complaints of:
1) Kids. During summer and holiday vacations, there are a lot more kids and an even greater chance of kids playing with the elevators.
2) Elevators with buttons that are too high to be reached by a wheelchair user. (okay, thread deviation here because that's no applicable to the non-disabled companion)
3) Elevator doors which close too fast. (again, not a non-disabled companion problem) We've had instances where wheelchair users nearly lost their service dogs because the dog walked in ahead of the roller. Better to have the dog walk in next to him/her if possible and use the chair to block the door from shutting.
