So here's where I am at the moment .....
I am planning a trip sometime late(ish) next year, possibly Sept / Oct, to India as a 40th b'day

treat to myself.
I have airmiles with AA that I want to use for a Bus Class BA award to India. I would then like to visit the Himalayas from there.
My initial thoughts were to visit Shimla and stay at Wildflower Hall after flying into Delhi.
I will likely have 4-5 days in total, and want to make the most of a trip to India & himalayas, without travelling every day - I would like a bit of rest too
Any thoughts or suggestions on this or alternative destinations, particularly in the Himalayas?
TIA !
Simla is Ok as Himalaya goes, but it will hardly give you a taste of what Himalaya is. Try going to Manali, and beyond, weather permitting, or to Laddakh. Manali can be done in 4-5 days. The drive to Manali, though rough, will take you some spectacular moments. If the roads are open, even Gangotri is doable. A flight to fro Laddakh is also doable in 4-5 days.
