bro DeepFuk,
actually if you are going for the 1st time (like me), meeting a JC girl is not a bad choice.. She can bring you around (SUPER GLUE

) but be prepared to meet her friends/parents for dinner.. I don't know why but con gai vietnam like to show off their oversea friends to their friends/parents.. mayb its their culture..
However, if you can meet up with SS or the rest, it would be the best choice.. Meet up with them for the 1st day then the remaining you can either meet your girl or ask the rest for places of 'interest'.
rgds,
vlover
