Yes, and it’s simple. To change the currency, please, scroll to the top right corner of the site, click on the currency you’re currently viewing, and select a new currency from the dropdown menu. The currency can be changed this way any time up until placing the tour in your shopping cart. Once a tour is in your cart, you may change the currency with the drop-down link directly above the Cart total.
If you book in a different currency than your credit card, your bank may charge you a currency conversion fee. This fee is generally per transaction, so you may be charged twice if you request a refund later. Check with your bank about their policy before booking.
