So let me try to wrap it up in a single thread.
At night we stayed in Gilgit.
Next day early morning we left for Islamabad and reached Chattar by night. The stay was in PTDC chattar and this is definitely not a recommended hotel because they were not having proper facilities.
Next day early morning we left for Islamabad and that's how our wonderful journey of GB ended.
Looking forward to go there again but this time by air or probably when they have proper CPEC road infrastructure in place.
