2 couples+ 2 kids each want to visit kerala in last week of december. Journey will start from pnvl & end at pnvl. My confusion is whether sightseening is from kanyakumari to ernakulam or reverse so that it is convenient ! Any local person please guide. If possible we have to cover rameswaram & madurai. Time limit 24/12/2014 to 02/01/2015. This includes train journey also.
