On every trip page you visit, you will see a button at the top left hand side of the page that says "Add to my shortlist". Click this button and the trip will be stored in your list, which is always visible on the left hand side of every page.

When you have finished shortlisting, you can click the "Compare these trips" button under your list and you will return to this page for a side-by-side comparison of your favourite trips.

As you compare your favourite trips, some may eliminate themselves. In which case, simply uncheck the box next to the trip name under "refine your list" and it will disappear from the screen. You can always re-check the box to bring it back again.

Once you've decided which trip or trips are best for you, click the "Book this trip" button above it and you will be taken to the "your booking" page to complete the simple reservations form.
