Some feedback from my travel around t¡bet for whoever might need it!!!
Firstly try to avoid joining tours at all cost, not needed in Lhasa at all and if you buy tour directly there is much cheaper!!
Get permit from any FIT agencies in Lhasa, try
fit0891@hotmail.com (you can call them at 0891-655-1841) . They will fax you copy of the permit, which is enough(noone acctually realy look on it anyway!) I got permit thru agency in Shanghai(
novawoo@hotmail.com - Avon) for 450RMB, if you get it from FIT above it shoudl be only 150. Make sure you will book permit and tour with one agent only, as I had really hard time to get new tour with local agent in lhasa as I didnt have teh contact details of teh one teh agent in Shanghai used.
Once there its easy to get bus from airport to Lhasaa dn find accomodation directly there. We stayed in double room right next to Jokhar temple for 70 RMB only, shared baths but very nice. tehy ahve teh best rooftop restaurant in Lhasa with exellent view. Dont have their phone number but try to search for Namchen House.
With the tour, you should buy it with teh same agent who made the travel permit for you. We payed 8000RMB for 5 days tours for 4 people so 2000RMB each. 3 full dasy of trekking, one day drive there and fifth day back. Price included guide, jeep for 2 days, 3 horses and all gear_tent sleeping bag/mat/ cook+plates. We had one horseman adn one guide. You can get simillar price for all major trekking areas, one agent offered us the same money incl cook and food!
Very big problem is teh attitude. Dont do anything at least for 2-3 days otehrwise you will finish with big headache. The same for teh trekking all routes are above 4500, take it very, very easy. Its Ok in the morning but evenings and night can be very painfull!!!
Godo luck with your trip!!
