Not to be an ass but AMS is actually a semi crappy international layover.
My airline decided to do the 'mini hub' thing so there's very little way of even avoiding flying there for the most part as we fly from AMS to darned near everywhere in the US, multiple times per day.
Downtown is fun, but it's like Tijuana but instead of drunken gringos, it's drunken, potsmoking Englishmen and Americans. The beer is good, but it's dirty, the weather blows and our hotel is like an early 1990's Ikea in the middle of a sketchy neighborhood.
"Meh..."
Now if we were still laying over in Den Haag, now THAT'S living. Far nicer neighborhood where I don't have to worry about stepping around dog poop and getting my head cut off, a nice beach, some really interesting bars and restaurants. Better hotel where they actually appreciated our service. The one we stay at, hell, the one my airline BOUGHT is under the same brand but their attitude is largely, "You own us, we manage the hotel and it doesn't matter as, well, what are you going to do, sell it and put an RFP out for 400 rooms that MUST come at a steep discount? BAH!"
About the only good thing about it is being able to score a hotel bike and high-tailing it into the countryside.
WMostellar knows what I'm talking about!
