A few of the regular rooms have a fridge. Room 19 I know does. All the suites have microwaves & fridges. All the rooms are nice. Yes you can charge food and drinks to the room and they have room service. Either currency works everywhere but my rule of thumb is if the prices are listed in $J pay with $J. If they are listed in $US pay with $US. That way you don't get confused by the conversion. On the beach the vendors will likely quote you $US.
