I love this site. I think I'm addicted. I've been doing almost nothing but reading all the trip reports and other great info for the last month. With your help, I've put together a 23 day trip to Vietnam (11 nts total in Vietnam including Hanoi, Halong Bay, Hue, HoiAn, Saigon, 3nts in Siem Reap, 4 nts in Bangkok and 3 nts in Chiang Mai. Will be leaving US on Jan 24 '09. Hopefully, the weather won't be too wet or too chilly.Mayra and others have been most helpful. I'm now re-reading for restaurant suggestions. Also, would like some suggestions on vaccinations. Will definitely be getting Hep A and tetanus/diphterra. Not sure if we will need typhoid or maleria. Any commentary on these would be greatly appreciated
