They are you typical Ford Crown Victoria/Mercury Grand Marquis cabs, so it may be a squeeze. However, bell services can request one of the van-cabs if you need it. I would give them a few extra minutes if that is the case. We try to be down at the cab stand no later than 30 minutes before our ADR at other resorts (we usually only use them when we're doing breakfast ADRs), so I would say maybe 40 minutes. Of course, you could also ask bell services on your way in when you arrive.
