2019 being a rough year, I was in a desperate need of vacation and Vietnam was in my bucket list since long. After some research found two way flight from Kolkata to Hanoi in 15k and booked it without giving a second thought.
Applied for approval letter, which costed me $8 and got in 2 days. As I would be returning from Hanoi, selected to visit north and central part, made rough itinerary of Hanoi- Halong bay- Danang- Hoi An- Hanoi- Sapa - Ninh Binh- Hanoi- Kolkata, download few apps like grab, Booking.com, klook and started my trip with a backpack.
Reached Hanoi in the evening, applied for Visa on Arrival for $25 (fyi, evisa cost $25 & no approval letter needed). Booked grab and headed to my hostel in Old quater.
Halong bay Day tour - Rs.2800 (included pickup & drop from hostel, explore halong bay, lunch in boat, explore Thien Cung cave, Kayaking or banboo ride)
Next day, got picked up at 7:30am. After driving for almost 04 hours, reached Halong city harbor and boarded wooden boat for Halong bay.
