Your guide portal is where your travel company shares what you need to lead their trips:
The portal carries your travel company's name and logo, and works on a phone, a tablet or a computer. A departure is one run of a trip on particular dates; most pages are about a departure.
Vendors working on your travel company's trips use the same portal. A vendor's home page lists the trips they are working on, and each trip opens to the same departure page that guides see.
If something here doesn't match what you see, or you're stuck, contact your travel company. Your contact for each departure is named on its page.
