Early in the morning we freshen up and went to famous Frank Ross Cafe for breakfast. After a heavy breakfast and some window-shopping on the streets of Darjeeling we started back for Siliguri. We had the lunch on the journey.
Now small brief about the cost of the trip:-
1. Kolkata/Durgapur to Siliguri:- Rs.1000/800 per person by bus (AC Volvo). One can take train to NJP but for sudden plans it's difficult to get a confirmed ticket. Though the train fare is much cheaper.
2. Siliguri to Darjeeling:- By Sumo or Bolero 150/- per person. Or you can book a complete car for 1300/- to 1500/-.
3. Hotel:- As per your bugdet. But 50-60% discount if you go in the off-season.
I completed the whole trip, Durgapur to Durgapur, in Rs.2600/-.
Hopefully this will help you, to plan your weekend Retreat to Darjeeling. All the best. Keep traveling.
