Hi Lain,
I'm thinking about the Dec departure as the weather should be a lot more bearable then! However, I'm also thinking about doing Nepal with Travelsphere in November, so it will be one or the other if finances allow!
It looks a great itinerary, so if I don't do it this year I'm hoping this holiday will be around for a few years and I get the chance to do it at some stage.
Hope you book and have a great time!
Best wishes,
Bob
