Answer:
Dear friend,....................
I hope you are doing well. I was thinking to invite you over for the holiday at my grandparents place in Manali The place is beautiful; as there are a lot of sights and fun things to do.
It sounded great to be able to together and just spend time together doing fun things. We can take walks in the afternoon and enjoy the mountain breeze, then have a bonfire at night.
I hope you find your place, and I would really love to have you there with me. if you can make it, and we can plan our trip together.
Looking forward to hearing from you soon!
Warm regards, [your name ]
