Favorite thing It is always very important you are healthy and wealthy during a visit to some other places. Carry cash, credit cards and now debit cards together with you. I think traveller cheque is a little bit out dated compare to 10 years ago. Some banker would need your activation acknowledment prior your departure, so you have to arrange for it before your trip.
Favorite thing I used to exchange my Malaysian Ringgit to Thai Baht before crossing to Thai boarder. I can get better exchange rate either at Changlun or Butterworth. Normally, I keep the remaining Thai money looking forward for a future visit.
