i went there around 2 yrs ago....its abt 2 hrs from gilgit and u can go to gilgit by air,coaster or ur own ride..if i remember correctly its 15hrs,im pretty sure its not doable in 11 ..kkh is pretty ok and u can go by car(dont need 4x4) unless u plan to go to deosai plains...there was a group of 3 guys from lahore who had made the trip on a cultus(just stressing the point that u dont need 4x4)...
For everyone who hasnt been there fairy meadows its a must see...the trek is 3 hrs tops for someone who has no trekking experience and is badly out of shape(that wud be me) women make the trip all the time and unless there is a pre-existing medical condition which limits physical activity,the trek is very muchdoable for ladies...
Like damriol said no hotels in fairy meadows but they do have huts apart from the tents...oh and as far as fairy meadow goes u need to take ur own food with u..coz the food they have there sucks big time...so take some tinned food....
Fairy meadows is probably the most beautiful place is pakistan....u'll thank urself u made the trip if u go there...the view of nanga parbat from fairy meadows is breath taking...base camp is arnd 5hrs from fairy meadows but the catch is that u have to get there and come back on the same day....and that may prove a bit too stressful for the wife...
P.S i recommend u go to hunza on the same trip....
