Withdrawing money daily is way too expensive, as well carrying your entire vacation spending budget is too dangerous. I heard of one unfortunate traveler who took the bus from Phuket to Surat Thani, left her purse in her checked bags (luggage that goes with the cargo below). She was diligent in watching the bus at every stop and ensured no one touched her bag; however, what she didn’t realize was during transport someone had climbed into the cargo compartment and went through her bag taking her purse and passport.
