thanks, this is really helpful. Your idea is intriguing about the airport hotel since we would be onsite for getting up early - I was afraid if we stayed overnight in Amsterdam proper we'd be in the same boat as leaving the ship (though perhaps not if the port is farther). This is probably a dumb question, but would you head to the Sheraton, drop bags, and then go in to Amsterdam for the day? Are there trains? I will research this but just in case you have done it.
