My husband and i will be flying into Singapore from Canada in March. We have 19 days to backpack around.We would like to fly Kuala Lumpur to Kochi India for 4-5 days to see Kerala backwaters but are stuck as where else to go.Travel via plane and sleeper train is best.We have been to Thailand 3 times and Cambodia once. Looking for a mix of culture/jungle/white beaches.I am feeling overwhelmed because there are so many options.I am looking for suggestions for the best order in which things should be done to maximize and not backtrack.Our budget is around $100 each per day. I know the questions are a little vague but i need to start piecing this together,we leave in 50 days! Please help.
