We didn't expect that our fishing charters would not take a credit card for the balance, so we were short on cash. Tips: The Bank of Costa Rica ATM daily max is $200. There is another ATM that we tried (green but I don't remember the name), and it would not give us cash, however later learned that ATMs can be out of cash especially on a weekend. Tried this same ATM another day and was able to get $200 from it. So, by visiting both daily, we were able to get the cash we needed. There were 2 fees each time totaling $5.50. Also, we went to a bank to exchange money, but didn't realize we needed a passport. Ended up using US cash anyway and that wasn't a problem.
