When you head back from Gili to Bali, all you need to do is be at the Harbor 1 hour before departure time. You need to register your departure details to the closest Fast boat office, available close to the Harbor. Ensure you have got your return boat ticket otherwise, you need to purchase it advisably 2 days before the departure date to avoid fully booked.
From Gili Meno port, the company will take the passengers using the smaller boat for 10 minutes ride to get into the bigger Boat then head to Bangsal, Lombok port. From there the fast boat hits Lombok strait to Padangbai Harbor in 90 minutes ride.
If your boat tickets are booked with complimentary shuttle service to your following accommodation, ensure to get on the official transport/vehicle service from the fast boat company. Otherwise, there are many freelance drivers in the Harbor who will try to sell you their service with some negotiated charges.
