We also use cash and travelers checks. No problem at all with TC's. Even the local grocery stores will cash them with ID...generally a drivers license is all you need. No need to take your passport. We generally stay pon da west end, both of the main stores on the cliff cashed them with no problem. The Banmark is probably a better deal but when in need...the others fill the gap quite nicely. A lot of folks don't use TC, but I feel much better having some along with me on the trip. Just be sure and keep the duplicates in another area...if anything happens, it is always so comforting to know that ya got a back up..unlike cash. Once cash is gone...cash finish, as they say in Jamaica. Have a wonderful trip!
