Thanks for your suggestions. Since the resort is an all-inclusive thing and we don't plan to rent a car, our out-of-pocket expenses should be limited to incidentals and souvenirs, so I hope we'll not have a big need for credit or ATM services.

I think our plan will be to carry a modest amount of $US in cash and contact the resort about using Travelers Checks or an on-site ATM for exchange purposes. If there's a slight differential in exchange rate to official rate, we'll call that "insurance". Thanks for the reminder on notifying bank & credit cards; although we'll hold them for urgent needs, it'd be then that we'd want to be sure of availability.

'Throwaway' wallets with minimal cash, expired ID and cancelled credit cards seem a good idea, and we do use security pockets for the real stuff.

Again, thanks to all; I'm looking forward to this trip, but wonder why they couldn't have chosen Hawai'i ...
