Just realize that the bus may be ready to go as soon as you and the kids arrive. Are you willing to stand there and wait for the next bus or are you going to get on that bus and have him ride the next one?
How many bags will your DH be trying to juggle? Can one person do it alone?
Me too. I've walked right onto a bus and been on my way. I've had it take 2 1/2 hours from getting off of the airplane to being at my resort check in desk.
