I want to know about the sleeper and luxury sleeper bus from Delhi to Rishikesh. I checked it on several online ticketing websites and it left me confused. Some operators are offering Delhi to Rishikesh ticket in AC Sleeper for Rs. 500 and other are offering it with different name Luxury AC Sleeper for Rs. 700. What is the difference between these two and which one I must go for? I have no issue with the travel time and travel duration. All I need is a comfortable and safe journey.
