If you want some relax time with less crowd, then go to Neil Island, Ross and Smith Island for amazing sunset, blue lagoon at the end of Elephant beach, dont miss Radhanagar beach. They also have a helicopter service which shows you the bird eye view of few islands.
Most definitely. It is perfect for a honeymoon. You'll love the pristine clear beaches and also a lot of activities that you can do there. You can refer this for some I sights. There's a video you can check to see how beautiful the islands are. https://www.tripoto.com/trip/explore-andaman-in-5-days-5d46b3bc2755a
