Booking your own travel makes you responsible for everything! It’s assumed that you read the confusing fine print and chose the right options with reliable suppliers. It’s assumed that you booked the right flights to connect with your cruise, or resort check-in, and made no mistakes with international documentation and more.
If anything is overlooked, misunderstood or goes wrong, you’d be on your own to fix it. Ask anyone who has dealt with nearly expired passports, volcano’s, late flights, missed cruises, airline strikes, lost hotel reservations… It’s a nightmare to deal with these things on your own.
When a travel consultant plans and books your trip, they are bound to represent and protect you before, during, and after. They leverage their clout with suppliers and make the most of their industry influence and training should anything go wrong.
