When we travel we usually pay for purchases with a credit card. Is that hard to do on Molokai? We don’t usually like to carry a lot of cash with us for safety reasons.
Many places accept credit cards; the grocery stores, retail shops, the lodging facilities, activity providers, etc. However other places do not – many eating establishments (Hotel Molokai & Paddlers excepted), street vendors and so forth. It is wise to have some cash with you on Molokai. Traveler’s checks are treated as cash.
Hope this helps.
