About Singapore Next Travel Destination? Vietnam?- dudunginside.blogspot.com

I plan to travel in April. I was checking out the flight tickets and I found some very good deals from Scoots airline. Wow it only cost about $100plus for return flight to Vietnam. I'm not sure if I should go as I be traveling alone as most of my friends are working. Maybe I do some research first before I go. But one thing for sure is I want to explore Ha Long Bay. My ex-colleague said it's a beautiful place.
