I’m gonna say this now, Vietnam is one of the most affordable countries to visit. Like no joke even from me as a broke boi. My hotel is 50-70 USD for 5 nights, it comes with free breakfast.
My recommendation is to eat: Bahn Mi, Pho, Coconut coffee.. Well basic AF but it’s popular for a reason. Ah and there’s a thing called Ba Na Hill, pretty nice and cool.. One one painful walking; Marble mountain, my knees died
