City sightseeing one day Havelock and Neil island two days Ross Island and north bay mangrove forests and lime stone cave mount harriat and Chatham saw mill or if you are enough lucky to get permit for Jolly buoy and redskin islands. (which is issued two days prior) those were our main destinations. and I think it should not be missed by anyone who visits Andaman. you can go through my blog on this. how to visit Andaman self arranged. my tour was of ten days and we didn't have a single day free. even we missed diglipur because lack of time. so make accordingly.
