One thing about traveling to Vietnam and especially up in Sapa... make sure you exchange a bit of money. Unlike Thailand where money exchange stations are abound, Vietnam don't have that much. I was in Sapa and couldn't find an money exchange place anywhere... They have banks that will do it but only on weekdays - I exchanged mine at the hotel I was staying in when I arrived there and at a jewelry store on Sat. - probably got ripped off but I couldn't get them anywhere else.
