Wow, that sounds like it's going to be a very... exotic
vacation! What made you decide on that locale? Will you be
travelling solo or as part of a group?
Travelling in Japan is not as expensive as one might be led to
believe. Hotel rates vary widely depending on the time of the year;
May is an off-peak travel time within Japan and I was able to
secure a decently-rated business hotel within a ten-minute walk of
the Shin-Osaka station for just US$29/night.
Food expenses can be kept in check by observing where the locals
go to eat, and doing likewise. Or buying food at the supermarket
and throwing it into the fridge in the hotel room.
It also helps that the US dollar is currently doing spectaculary
well against the Japanese yen. During my last trip to Japan, it was
76 yen to the US dollar; it is currently about 95 yen to the US
dollar.
I'm trying to discover the Lost Horizon - The Shangri-la lol.
Anyway I had covered some of these area including Lhasa (Potala).
Rongbuk (Everest Base Camp), Mt Kailash, Guge Kingdom,
Lo-manthang... still more to go...
