I have heard a lot about Andaman Islands, from friends to colleagues, from boss to juniors. So I was also planning to visit Andaman since a long time. During September 2014, we finally got the chance to explore this place, largely thanks to SpiceJet ticket sale, which helped us in keeping the package cost on lower side :-)
What made it special - We booked the land package from a local tour operator and got the best deal and since I booked this in advance so they upgraded the rooms and also the cars. Also we booked a dedicated car instead of SIC basis so we enjoyed a lot.
We visited 3 islands during our visit to Andaman Islands, Port Blair (3 nights), Havelock (2 nights) and Neil Island (1 night). Out of all of them Neil island can be skipped if you are short on days and also it only offers beaches and views and water sports, which you can also get in Havelock.
Tips - Try to book the package from a local tour operator, as they have all the local knowledge and it will be cheaper for your pockets also.
Tips - Try to book hotel Port Blair hotel within the city. We booked hotel on top of a hill (even though the views are great) so we have to walk 30-35 minutes before we can rent a vehicle. Also on the hill, hotel rooms are closer to nature and more closer to mosquitos and all sort of insects.
Tips - Bring lots of clothes as all the activities are on or in water, you will get soaked and there is no laundry service in most places.
Tips - Bring a lot of mosquito repellant and sunscreen cream and a torch, there are no street lights in Havelock and Neil island and basically no nightlife in Andaman.
