did you try getting flights to eindhoven and get a 40minute bus for around 15euro return to amsterdam? if ryan air have a deal on ull get the flights for 50-70 euro return, as for accomidation yea your pritty screwed on any mad event but i use wotif.com to find hotels over there, i got a 4 star carlton hotel for 100 a night for the room. but it was around december off peak really.

YOu dont really put it in your shoes do yea i put it in shampoo bottles or even better if you can get some skin ointment, something as thick as vasaline and put it right in the middle of a big tub, the plastic is very thick on the large tubs and no air moves around in something as thick as vasaline so its more air tight then you shoes and bleach the outside of the ziplock or what ever bag you have them in, then im sure ud even get away with it if a sniffer dog came over to your bag. I walked straight through two sniffer dogs with a couple of grams in venice (venice stoned is amazing) but now i did have a streak of shite following behind me and my heart was going about 200 beats
