If you see my post above, I have just proposed the "little gems hostel" as one of the places he can visit, and have not solicited for any form of donation. I agree that he is going for a holiday, but does that mean he can not visit hostels with a cause? It was just an idea to help him see the nepal which tourists normally tend to neglect.

Drmana, I do not mean to offend you, I am just clarifying my point here.

Shapil, you can cash in Traveller cheques in any bank in kathmandu but you will be better off carrying USD in cash, which is accepted widely in tourist areas.
