Hello Hoai,

Thank you very much for organizing such a great interesting Vietnam tour. I'll write an excellent review for the Tripadviser.  

We are going to have a party, where we'll tell our friends about Vietnam, show pictures and cook some vietnamese food. Some people already interested to go to Vietnam and asked me your email address. Hope more my friends will want to travel to your beautiful country.

Thank you.
