Recently I visited rameshwaram with my family, it was nice experience at rameshwaram. You can visit main temple and remaining places within half day. The main temple opens at 6: 30am in which holy water of 22 wells will be sprinkled on devoties one by one in the temple to complete this part it will take almost 2.5hrs and then you need to changer your clothes and wear fresh clothes to have main temple darshan which takes heardly 30mins. And then when you come out there will be many auto rikshaw guys will be there who will take you to the places to visit like Ram temple, Ram kundh, Radha krishna temple, pancha mukhi hanuman, Rama sethu. Which will take hardly 3hrs. They will cost Rs.100 per person to visit 12 places one of them is KALAM SEA SHELL where Abdul kalams museum is there, there we can see Abdul Kalams pilot dress and the books in which he has done rough work and many more. In the upper floor there will be a shopping centre where you will get original pearl jwellery and shanks and the price is fixed and that shop is just to maintain museum.
