Trip to Vietnam/Thailand!

Hi everyone, So, my partner complained to me that we barely go for trips abroad and maybe this year we should visit a south east asian country, even I felt the same 😅(I am a baniya by nature not by caste🫠). I tried looking for options and I think I would like to visit either Vietnam, and/or Thailand(but I am not sure if my partner would like the idea of Thailand due to its image in middle class families 😅). I thought I should plan it myself since the ones selling packages seemed a bit over the budget but got very confused regarding the authenticity of anything online. Anyhow, long story short, I am looking for suggestions or anyone who could help me plan this surprise trip in December or maybe refer some travel agent or any specific package which they have purchased themselves in past. I would really love some help on this, will treat you to a Pizza/PaniPuri 😁!!

Open to suggestions. Dm's are open as well.

Preference - 3/4 days only since my budget is small😅.

And we are vegeterians!

The trip has to be in 2nd week of December 😅

Thanks! Much love beautiful people!
