I'm doing this next week (LYS-AMS-BUD). I have been to Schipol dozens of time in my life but I've never actually visited the city itself, and I frankly don't fancy spending 5+ hours in the Crown Lounge again. My flight to BUD departs at 9pm, when should I be getting back to the airport, considering that it's a Schengen flight and I have SkyP? I was thinking taking the train around 7.30pm but that might be pushing it a little bit...
