Yes, I did K2/G La with VE in August.
http://www.vepakistan.com Fantastic company and what a fascinating country. The people, the history, the food, the architecture and of course the ability to step back in time and witness valleys untouched by western consumerism is something to experience first hand.Will definitely use them again.I thought they just planned better and appeared to be good employers. Our cook, sirdar and guide had been with the company for many years.
The staff on the ground in Islamabad & Skardu were also great. Even after our tour ended, we were in Pakistan for a further 5 days and they still sorted things out for us.
Also quite a few of our fellow trekkers had used VE on other occasions.
Cannot rate them any higher!
