I’m going to Hanoi & Hoi An in a couple of months’ time. I’ve heard it’s cheaper than the UK but trying to work out how much I should take with me. Please advise how much alcoholic/non alcoholic drinks are, how much it is to eat out in restaurants for these two locations and is it cheaper to book trips to Ninh Binh / Halong Bay or Lan Ha Bay once in Hanoi? There will be 3 adults going for 2 weeks. All accommodation paid for already, Thanks
