Is this possible (european vacation)?

for one there is the problem of the cash as you can only take a cetrin amount and i dont think it would be such a good idra to have 10 grand on u at all times allso you woulld need visas to stay there which wouldnt be to hard to get. the whol thing of stayhing in hostils is good as thay dont cost much but u will need food so 10 grand is not going to go far u will at best get like 1 mounth out of it
