Yes! You can quickly Preview an itinerary that you are working directly from the Itinerary Builder. Here's how:

Open the Trip and click Preview, next to the Send button.

This will open the itinerary in a new tab. You can look over the itinerary here or copy and paste the URL and share the link in a personal email to your clients!

If you have made use of the tags feature, you will be able to review the itinerary for each traveler in a large group trip, as well. At the top you will see the option to preview each itinerary as different travelers, as seen in the screen shot below.
