I am trying to find out the price of Costa excursions before deciding to book a cruise. There is a link: https://www.costacruises.com/excursions-results.html where I can find the excursions (search based on destinations) but the price is not displayed. I know that of I had booked a cruise, in mycosta I can find out the price of each excursion. But how can I find out if I don't had booked yet the cruise? Thank you!
