I'm making flight connections in Amsterdam and have only about 8 total hours between flights. Is it possible/easy to get from the airport to the city in that time and actually have time to see something? I've visited the Anne Frank house in past years and, although that might be worth seeing again, I would prefer to just get a quick look at the city--like maybe on a boat tour. Any suggestions? Is there a way to do this without making reservations in advance, in case my flight schedule gets messed up?
Thanks for your advice!
