Thanks Marco good advice. For one I plan to take a sleeping pill before my plane ride at the airport. This way I can sleep the 8 hour flight and wake up in Dam. I should get to the book store and get a guide book.I think your mistake last time was two-fold, making it a weed vacation only, and not being prepared. Get some guidebooks on Ams and read them before you get here, make a plan for stuff you want to see. And wait to smoke up until you have settled in, taken a shower/nap and walked around a bit.
