Hi Caroline, I'm new to this forum but not to JustYou holidays, having done a couple already. I am also booked for Vietnam, but going 17th September. It's been on my list of "must-see" places for ages, so really looking forward to it. I have a few friends who have been and say it was their best holiday ever !
I'll be back before you go, so if there's anything vital that you might find useful, I'll let you know. I noticed on the main holiday page on the website, there was an article in the form of Q&A's from previous travellers there, which I found really useful.
You'll be fine. Most people that come back from their first 'solo' holiday wondering why they didn't do it sooner 🙂
Jacky.
