I was in Frankfurt less than 24 hours so I don’t have a lot to say about that. Le Meridian Park is conveniently close to the central train station and my corporate hosts took me to a very nice Italian restaurant.
Frankfurt Airport is a pit of hell. In retrospect I should have figured out how to get to Amsterdam by train. Perhaps other gate areas are better, but D is an endless corridor with no waiting areas or shops; these things have been replaced by glassed up smoking areas that smell, even from the outside, like stale ashtrays. Bleak as anything.
I am currently relaxing in the lobby of the Schiphol CitizenM. It’s like an upscale youth hostel with relentlessly cheery staff, a canteen, and several doses of hipster. I like it a lot. Also free movies which will come in handy if I feel too sick to bop around Amsterdam tomorrow.
