Trip to GB in April

Guys I’m planning a trip along with my family to visit some places in GB i.e, Hunza, Skardu, Shigar, etc. So we’re travelling from Islamabad and we have a week, I could really use some help. 1. I’m aware that there are some good places to stay at in these places like Serena in Hunza or Shangrila at Skardu, but I would appreciate some more suggestions for other places where we could stay and explore this region. 2. Is it a good idea to drive ourselves from Islamabad to GB or to hire an experienced driver, my brother and I are pretty decent drivers but obviously we’ve never driven on this route before. 3. If we break our journey into two parts when we’re driving from Islamabad to Hunza, what place would be decent to stay at and would have good hotels?

Any other suggestions are also welcome.
