Took a direct flight to Guwahati from Mumbai at 7.10am Indigo.
Reached Guwahati @ 10.10am.
Took Ola and went to AWE Rides where I rented a two wheeler for the trip.
Had Breakfast (Maggi) in nearby restaurant.
It will take 3 hrs if you drive continuously from Guwahati to Shillong.
Remember Sunsets around 4.30-5pm.
On the way you will be able to see Umiam Lake.
So if you reach Shillong by 3pm you can cover Shillong View Point and Elephant Falls.
There are few more places like Ward's lake, Churches n Museum.
(I was not able to cover up these places due to unexpected circumstances at stay which I booked through MMT)
I stayed at OYO Balaji Guest House overnight.
You can have amazing foods near Police Bazaar. There are less options for Veg in Meghalaya.
You have to depend mostly on Maggi.
