We flew from New Delhi to Kathmandu on Nepal's airline (Royal something or other). Had an awesome view of Everest departing to BKK. Do you have hotel yet? We were there about 5 yrs ago and the choices were dismal - water really yucky. After India, Nepal looks clean but do not be deceived. I recommend Yak and Yeti for hotel - well located, restaurant pretty good. Annapurna is to be avoided at all costs. Food looked like poison and water so dirty I would not even bathe in it! You want to be right in town where transportation is easy and cheap. Look out for the yogi at the big Hindu temple outside town. Very weird. Condi Nast Traveler did an article discussing this guy.
