Some advice. Traveller's checks can really only be cashed at high class hotels and banks. Most Bujinkan members don't stay at the former. Either carry around several days more cash than you think you will ever need and/or be damn sure you know when the bank holidays are. I just talked with someone who spent all his free cash on Sunday night a few weeks back thinking he could get his TCs cashed the first thing next day. It was a three day weekend and Monday the banks were closed. He had a heck of a time and had to be saved by other Bujinkan members. It is better to have money in your pocket and not need it than vice versa.
