I'd love to see a dedicated client to-do list built into each trip. This would give clients one place to see exactly what they still need to complete instead of searching through emails.
Examples could include:
Complete traveler information
Upload passport information
Make a payment
Complete online check-in
Book dining
Purchase travel insurance
Ideally, advisors could create custom tasks, assign due dates, and mark tasks as complete or allow clients to check them off themselves. This would make the planning process much clearer for clients and cut down on reminder emails.
