re:
The wx tends to be little nasty in the late afternoon these days and sticks around Nopen (16 NM South to KTM). Morning arrival are prefered if you are coming here for the first time. Stay right on the 022 radial and don't bust the minimums and watch out for the ridge at 8 dme on Vor dme rwy 02 approach.
The place is crowded but not as polluted as few years back. Hyatt Regency is a nice hotel to stay at which is in Boudha.
Handling is pretty quick if there aren't more than 2 international arrivals together.
What else .....I guess that about it.
