We are travelling to the Arenal area, and will be staying at a few different hotels over our week-long trip there. (Tree Houses Hotel, AOL, and The Springs). We have not pre-booked any actitivies but plan on doing zip-lining and whitewater rafting, and possibly some other activities as well.
I am wondering if most of the restaurants and activity places there will accept US Dollars? Will I pay a premium for paying in USD versus Colones? Can I tip in USD?
