Example: One cruise line advertises its 100+ day around the world cruise for $22,999 per person. Of course, “price based on double occupancy and not including taxes, fees and port charges”.

Hey, senile sailor, you can sail on that bargain voyage with your cabin mate, but with those and unadvertised add-ons, you’ll each have to shell out $30,000. Or at least $29,999.99. Before booking flights, cruises and other vacation packages, demand the actual total out-of-pocket prices you’ll have to pay.
