I have already been to Bhutan during Dec 2018 (winter) and I am planning to go again in June. We can connect and discuss further if you are interested. Message me on tripoto or you can find me on instagram @lifeoutsidecubicle
All I can think of right now is Gokarna or any of the coastal towns like Karwar. Both the places have pristine beaches. Gokarna is famous for its laid back lifestyle and tanquility. In Gokarna there are 3 famous beaches - Om,Kudle and Gokarna town beach along with paradise and half moon beach.The latter two can be reached either by boat through the sea or by trekking .This is kind of off season in Gokarna so the beaches will be deserted,some foreign tourists might be spotted though. For best experience stay in one of the shacks in Kudle beach.
Yes you can add hashtags in your trips,infact whenever you participate in contests you need to put a certain hashtag so that they can reach your content.
You'll get good network in kasol, tosh has also average connection but you wont find proper connection during kheerganga trek and in most parts of malana trek .
Guwahati airport to shillong, u might have to pay 1500/1800 for full cab..... if u want sharing cab, that's also available at the airport without prior booking in 400rs per person. shillong to cherrapunji also approx 2000 Rs with sightseeing around cherrapunji.
If you plan in a right way, and take train for traveling, you can visit "Dehradun, Rishikesh, Haridwar"; "Jammu and Vaishno Devi trip"; and "Shimla" for 3 days.
I'd travelled all these three localities with 4 members of my family in just 20-25k for each trip.
It would take 1 and a half hour to reach Mussoriee from Dehradun from bus and would cost around INR 45-60. However if price is not a major concern you can go for taxi for a more comfortable trip and that would cost you between INR1000-1200 , shared taxis can cost you a bit cheaper though.
