If you decline the beverage package, you can always just "pay" by the drink onboard which will come out of your OBC. That's what we are doing with an upcoming cruise.
Is there any advantage to signing up prior to my cruise versus signing up while on the cruise? I used it last fall and signed up onboard and it worked great. Thanks!
Mendenhall Glacier is 13 miles from the cruise dock. You would be walking along the road. I don't remember seeing any paths or sidewalks along the route when we went last October.
