@Aidan in HCMC
The destination is Ha giang which I think happens to be a tourist destination for motorcycles.
I thought to go from HCMC to Hanoi by air and take a bus for the remainder. An thinks we can go by bus the whole way to save money but that would have tp be like 3 days which is Nahhhh. A train might be more acceptable but she seems to not consider train travel. - @Dannyroc3
(I've been through this with my wife)
No matter what you want to do in Vietnam, she is always going to want you to "save money" and she's never going to want to try a new experience when she knows an old experience that works.
I had to make it clear that if I wasn't comfortable and enjoying myself, saving money wouldn't be a good thing.
Since I have traveled between HCMC & HÃ Ná»™i many times, I would recommend:
1. Because you really do want to see the country, I would recommend hiring a private driver. It's definitely the most expensive option, but so many of the amazing experiences I've had in Vietnam have been with a private driver taking me to places that I never would have seen had I flown or taken the train.
2. However I'm going to guess that maybe that's beyond your budget or maybe you're going to let her talk you out of what you want to do, so my next recommendation is...
TAKE THE TRAIN!
It's (usually) a once-in-a-lifetime experience that can be done on an uninterrupted ticket from HCMC to Hà Ná»™i, or can be planned out with stopovers in interesting places such as Nha Trang, Quy NhÆ¡n, Äà Nẵng and Huế.
The train normally has three types of tickets: sitting in a train car with many rows of two seats each on both sides of the train, or in a 4 berth cabin or a 6 berth cabin (similar to military troup trains).
She would probably want you to take the cheapest option which is the seats in the open car.
We usually travel in the four berth cabins but recently the railway lines has done some upgrading of certain cars and now you might find a train that has a two berth cabin upgrade available.
We've tried those a couple of times and it's nice to have the privacy since in a 4 berth cabin, you have no idea who might be sharing your cabin with you.
NOTE: Many of the VIP options are only available on longer trips.
3. Or just fly. I personally love business class flying from HCMC to HÃ Ná»™i on Vietnam Airlines. If you decide to fly you should first join the frequent flyer club of the airline you choose. I know Vietnam Airlines gives an extra discount if you are a member of lotus miles and you book online or through their app.
OR...
4. Do a custom combination of 1. and 2. and 3. above:
For instance, you could take a private car from HCMC to Nha Trang and see a section of the coastline that many foreigners never experience, especially if you detour to VÅ©ng TÃ u first and then head up the coast from there.
Then you could fly from Nha Trang to Äà Nẵng
explore this area, maybe even seeing Há»™i An.
Then take a private car over scenic Hải Vân Pass on your way to Huế and then take the train from Huế to Hà Nội.
A decent tourist class hotel there can help you with all of your plans for your trip up to HÃ Giang.
