We're coming in for 10 days, 2 of which is not at the resort, but in the city. How much cash do we need to bring with us? Planning to do a little shopping and will have to eat, etc. for the two days we're off property. The other 7 we won't be leaving property. Also, if we do anything else (SCUBA, SPA, Etc.) at the resort, can that be charged to the room and settled with a credit card when we leave? Thanks!!
