Help with honeymoon to Vietnam

Hi everyone!

I am reaching out for some help planning our honeymoon to Vietnam. We will be there for 15 full days and while we want to see as much of the country as we possibly can and are okay with travelling via car or plane between in-country destinations, we are trying to avoid feeling like we are completely rushing from one place to the next. For some context, we are 32 and 36. We are not much of "hang on the beach for hours" type people and are looking for a honeymoon that has a mix of culture/history, city life, maybe a couple of days on the beach, and then of course some more romantic time immersed in nature. While we definitely want to see some tourist destinations, we tend to enjoy the more "off the beaten path" places. Here is what we have so far and would definitely appreciate feedback as far as places we may want to spend more/less time in – places we maybe SHOULD have on here that we don't – really anything we may want to be aware of. Our flight flying in and out of Hanoi have already been purchased.

Thank you in advance!!
