My grandparents are interested to go for a religious trip to Madurai and Rameshwaram. We are based in Chennai and plan to use public transport for this trip. We have booked train tickets for Chennai to Madurai journey on Kanyakumari SuperFast Express (Train #12633). The return tickets from Rameshwaram to Chennai are also confirmed on Sethu Express (Train #16714). But we could not get confirmed train bookings from Madurai to Rameshwaram. There are passenger trains between Madurai and Rameshwaram, but those only have unreserved compartments. I have heard that the trains from are usually jam-packed. My grandparents are quite aged now and travelling in unreserved compartments is out of question. So I was searching for information on Madurai to Rameshwaram bus service. How long does the bus journey take and will it be suitable for elderly people? I am looking for a comfortable bus journey, and wondering if there is any Volvo bus service between Madurai and Rameshwaram? Please let me know any information that you might have on Madurai to Rameshwaram bus service. Thanks much.
