KKH is a bit pathetic between Besham & Chilas. However work was in progress, don't know current situation. Chilas to Raikot is just ok.. and ahead of Raikot is excellent. However, from Nomal you will need to hire 4x4s as bus won't be able to make it to Naltar.
45 people would fit in a bus. Coaster is only 25 seater.
Many budget hotels available in Naltar. Don't know the contacts because didn't stayed in one. @versitian apnay Naltar hotel ka number bta de..
Yes you can visit in January and can witness snowfall. There is a ski resort in Naltar too owned by Army (NLI).. So if you have any contacts in Army, you can probably enjoy skiing too.
