Hi, i'm planning to go a maybe a week max holiday to either Viet/Thai and this is going to be my first trip so thinking of joining a tour.
anyone can recommend me trustworthy travel agency?

and if you don't mind me asking, what is the standard budget for maybe 4D3N holiday tour?

i've searched before for recomendation thread but only found thread on bad agencies (as pinned), so would really appreciate it if anyone can help.
thanks in advance
