Great to see you all and thanks for the pint Weedy
Loved supporting. Might have to re-think the whole running thing. Glad we could be of help, although not sure we did much. The megaphone was the best 8 euros I ever spent though, and it was great to see people laughing at the banners and even stopping to take photos of them.
Metro will be busy but not so bad from Waterlooplein. It usually gets busier at the main change points such as Zuid. You should be fine wherever you go from but as always leave a bit of time to get there
