Beautiful the Andaman Islands are. Havelock is really good, but you can also think of visiting Neil Island if you're thinking of a new location because Havelock has become pretty common now.
Transport in Port blair - autos are easily available
Transport in other islands - you can easily hire a 2-wheeler
Oh yes then that could a little issue in the other islands that you visit. However, Port Blair you can easily get transport. I didn't use any tour package because it's not like the place is too big and you'll get confused as to where to go. But if parents are coming along, then you might as well check a tour package so that your transport could be taken care of.
Actually I'm going with family.. a short break kind of..so two wheeler is not good idea. I have to think of other members as well. so the transportation is easily accessible there right? no need of tour packages?
