Hello, please check out my trip and itinerary here: https://www.tripoto.com/trip/where-sky-and-sea-meets-andaman-tales-5d2dc5d5c26a6?utm_source=Android_App%26utm_medium=whatsapp You should book ferries in advance to skip standing in long queues but Govt. ferries, I don't think you can book in advance. We booked private ferries in advance. I have given official site link in blog, check out price lists and pictures to get more detailed information. Also, I can help you with itinerary if you need further help.
Private ferries you can book online to avoid standing in long queues. water sports your choice, better book in advance you might get some discounts.. https://www.go2andaman.com/ferry-services-andaman/ message me, i can share few more related links
