travelling in October/November this year for the first time to Vietnam for our honeymoon.
We're going HCMC-Hoi An - Hanoi - Halong Bay - Hanoi - HCMC. We're going to be spending 4 days in Hanoi, 2 days on either side of Halong Bay - any suggestions or day trips anyone can suggest? Is 4 days too long in Hanoi? Any advice would be appreciated
