Hi all who've written re Vietnam.
I went in May just gone & had THE most fantastic time, I'm sure you will too. It won't be so hot in Dec. as it was in May which is lucky for you - around 22C in Hanoi getting hotter the further south you travel. In May it was 38C in Hanoi rising to 42C in Ho Chi Minh City & a sizzling 47C in Angkor Wat, Cambodia. Also incredibly humid which makes it feel even hotter.
The food is lovely so you'll enjoy the Culinary side of it and the places you visit - well exotic, stunning & very exciting.
You'll also be in bartering Heaven getting some great bargains!
Take Immodium with you - we all needed them, also antiseptic hand jel. We didnt need Malaria pills.
Have a fantastic time, I've had 5 holidays with Justyou & loved them all. Try the Thailand, Cuba & South African Explorer ones - all excellent.
