Hi Mike
Have been reading this thread with interest as I love Nepal and have been twice, once with TS in 2010 (JY didn't do the tour we wanted) and again with a different company in 2013.
For what it's worth I would like to say that when we went in 2010 we all did the optional Everest early morning flight. The plane held 22 people and there were 22 on the tour. Yes,it was interesting but difficult to see which mountain was actually Everest even though there was a map of the mountains on the back of each seat. We took it in turns to go to the front of the plane to chat to the pilot. Yep, it was good but the following year one of the Everest flights crashed and killed all the tourists, the pilot and the only cabin crew member. It was full page in the Metro and I sent a copy to the pal who I had travelled with, saying it might well have been our plane.
We went to Pokhara airport and,as Angie did, some of us booked the microlight flight and some of us booked the little two seater yellow plane which flew directly up to Machhapuchhre (FishTail). So much closer to the mountain peaks. That plane flight was awesome, much preferred it to the Everest Flight-if you book Nepal I can give Dave the details of the Aviation Company to forward to you although I am sure JY won't be too happy -you would need to sign a disclaimer, I think.
As for Phewa Lake it is easy to have a boat trip on it. Pokhara isn't very large and safe enough to walk around independently.
Personally, I don't think the shopping stops will affect the ratio of men to women on this tour, because as you and I both know there are always invariably many more women than men on JY tours (Burma was an exception).
I am looking forward to seeing the Himalayas again on the combined Darjeeling railway and invitation to India tour. I have seen a couple of TV programmes about the railway and the scenery around Darjeeling looks spectacular.
Best wishes
