The Savoy also has a great spa called "Akasa the Spa" which should be visited by all those staying there so that they can relax and rejuvenate in the region.
For all those on a budget trip..
For all those on a budget trip, I would still suggest you to stay at the Savoy. But if you can't, there are various options around Mall Road. Hotel Wildflower offers rooms for as much as INR 1000 per night. There are many more hotels on Mall Road which you can visit and are super super cheap.
Things you have to do with your friends there? To make great memories.
No trip to the mountains is complete without Maggi. Do not ever forget that.
You have to walk around Mall road and find your own echo point and shout out your name. Catharsis.
You should take a break from your friends and walk alone for a while so that the mountains can speak to you. Let the mountains talk to you and see how nature offers you advice.
