Hi everyone!
We're a group of 15 university friends from Karachi planning our first trip to North of Pakistan in mid April '17.
Dates: 15th April - 30th April
I've planned an itinerary and put a lot of research and effort into it (my major source was PW Forum), I wish to make it perfect and hence I'm sharing it here to get any sort of advice I can from the travel gurus here.
Following is the planned itinerary;

Questions;
1) First of all I'd like to know if my trip is too hectic overall, even for young university students? If so, what changes should I be making to make it bearable?
2) What places are there in Rama to stay? I know about PTDC Rama, but that opens in May. Also read about a PWD Rest House, can anyone tell me how to book that?
3) What is there to do/visit/spend time at in Astore/Rama?
4) At Day 4, is it possible to leave Astore/Rama at 11 and reach Skardu by 7/8pm?
5) What are the charges for Jeep to Deosai?
6) Is it possible to cover Manthoka Waterfall, Shigar Valley and Trek to Jarbazoo Lake in a day?
7) Is it possible to travel to Upper Kachura on coaster? Or we'd have to take jeeps(charges?)?
8) We're planning to stay at Hunza Huts.They are offering us a cottage of 6 rooms along with breakfast and dinner for 15 at 21,000 per night. Is it worth it? Also, is it located at a walking distance to Eagle's Nest?
9) Someone told me that the road to Eagle's Nest is very steep and cannot be done on foot or on coaster, is that so?
10) On Day 9, someone told me to do a Passu Lake trek, but I couldn't find any Passu Lake on google, was it meant to be Borith Lake? Are there any other treks to do the after our stay at Sost/Passu?
11) Is it possible to do Day 10 in one day? And what is there to do at Naltar. Or should we rather just keep a rest day before doing Fairy Meadows trek if Naltar isn't worth it.
12) What places would we be needing to hire jeeps and can you mention charges as well?
13) Is it possible that we find Babusar open on the way back (28th April?
14) We've kept a 35k per person budget from Pindi-Pindi, should that be enough or should be increase it a bit?
15) Any other words of advice?! 
I know that's A LOT of questions, but if each guru could answer a few, that would help a lot!
Thanks A LOT you guys!! :))
