We still use traveller checks - cashing them mainly at the casinos. We bring about $800 cash with us for 2 weeks, use credit cards (no fee), and the travelers checks. I don't trust the ATMs - we had an ungodly mess one year after using one. I know tons of folks use the island ATMs without any issues but I'm scarred for life. We also hit the casinos and there's no way I'm carrying that amount of cash we use gambling while traveling. It is way more difficult to use the checks when out & about - something to do with one of the island banks no longer accepting them (if I'm remembering correctly), which is why we primarily use them at the casinos.
