There are reasons why we almost always (99 times out of 100) go in early and leave late. Unless it's a port we really have NO interest in ... which has almost never happened. You can spend at least a night in town, visit the port and schedule your flight accordingly without worrying about getting there on time etc..
Having said this, I do realize that not everyone has plenty of time to spend this way ...and if you have to get back the next day, you do. But Amsterdam is a great city and well worth a visit ... Again, perhaps you've been there a number of times and there are other reasons why you want to get home ASAP
