Warning: Since Babusar top won't be open for another month, I would advise against traveling with family/children via the Dasu route for now.
Two dams Dasu and Diamer/Bhasha dams are being constructed on that road, so there is a lot of heavy equipment there and road is quite bad on several stretches from Dasu (town) to close to Chilas. Also there are no decent restaurants or bathrooms in that area. We were all guys so managed it but can't imagine going that route with females or children.
Staying at Chilas: Chilas is hosting a lot of wapda employees working on Dam sites since there aren't any decent hotels in Dasu. So all the good hotels are taken by wapda. So you're left with lower quality hotels.
