As we offer you the same prices as the tour companies, we don't increase tour prices to offset credit card fees. The 4% fee is what the credit card company charges us. Many of the tour companies also charge credit card fees, and many banks charge a transfer fee for paying in a foreign currency (you pay us in US dollars).
Please note that you can avoid the credit card fee by paying by echeck, check, or wire transfer. If you pay by one of these methods, the credit card fee is not applied to your $200 per person deposit.
