Motion sickness during the sea journey may be a troublesome experience, but few tips might be handy. Never plan your first sea journey during the period of April to June months - the sea is known to be rough during this period. Unless you are a habitual ship traveller, don't underestimate your body - in a 3-days journey due to the rolling and pitching against the sea (Local 'Hindi' term is for rolling and pitching is 'Halfa' or 'Halpa'), motion sickness may set in any healthy being. Consult your family doctor for advise on which motion sickness pills are suitable for you. Remember to start the anti motion sickness drug(s) at least half an hour before boarding the ship. Do not forget - these drug(s) work best if it is started prior to the start of journey. If you start the motion sickness medications after the motion sickness sets in then the drug(s) may not help at all. All passenger ships employ a doctor on board for the passengers (free of cost). Consult the Medical officer inside the ship when required.
Andaman and Nicobar are a vast archipelago, and aside from some erratic, infrequent and expensive helicopter shuttles and a pricy seaplane service to Havelock Island, passenger ferries are the only way to get between the islands. There is also the Infiniti Liveaboard that makes trips to destinations such as Cinque, Barren, Narcondam and other islands. In high season demand often exceeds supply, so book your tickets at least one day in advance, either through a travel agent or directly at Port Blair's harbour. Ferry ticket booking has now been computerised. This means you can book any ferry from any jetty - i.e. Rangat to Havelock from the Diglipur ferry jetty.
Auto rickshaws are available at Port Blair & Havelock island.
Taxis are available in Port Blair. Drivers double up as guides. A.c. taxis are also available.
Scooters & Motorcycles used to be available for rent in Port Blair, however, its not very easy to get one now. Auto-rickshaws may be the best way to move around the city. However, in Havelock Island they are the best option to enjoy a ride to the Radhanagar beach or around. It may cost you around Rs. 150 - Rs. 250 per day with a security deposit of around Rs. 750 - Rs. 1000.
