How exactly does boarding work?
Concerned about boarding and mobility issues, I've been unable to learn exactly how the boarding process works on Holland America. My particular concern is with boarding in Seattle, but it may work the same elsewhere...don't know.
How long is a person likely to walk from shuttle drop-off to cabin? How long should one expect to stand in line in the boarding process (or waiting to board)?
Any other tips for those with moderate limits on mobility?
