Two of us are travelling w/ out guide; headed to Lijiang tomorrow via Kunming. We want to go to Lhasa next week, probably from Chengdu. Any individual travellers that have done this in the last week or so, i would greatly appreciate your advice. We don't mind hiring a private guide for Lhasa if that's required to get in but otherwise, what guesthouse/travel person should we use in Chengdu to get our permits and tickets and who's reliable. Thanks so much.
