Itinerary

Initial plan:

. West Coast - 02 Jul to 06 Jul
. Hong Kong - 09 Jul to 14 Jul
. Tokyo - 16 Jul to 21 Jul
. Shanghai - 23 Jul to 28 Jul
. Jishou - 31 Jul to 02 Aug
. Beijing - 05 Aug to 08 Aug
. Lhasa - 12 Aug to 16 Aug
. Beijing - 18 Aug to 19 Aug
. London - 21 Aug to 23 Aug
. Istanbul - 25 Aug to 01 Sep
. Amman - 03 Sep to 08 Sep
. Dubai - 10 Sep to 15 Sep
. New York - 17 Sep to 30 Sep

Most of the trip was booked through oneworld.com so the dates are pretty much set in stone BUT the travel plan inside China is still fuzzy. Is Lhasa worth visiting at the height of the tourist season, given that all the government regs basically make it impossible to go off the beaten path?

Suggestions welcome.
