If youre going to HCMC, i highly recommend checking out the Ho Tram resort for atleast a one night stay.
They shuttle you to the destination and back to drop off point free of charge. (~2hrs)
I was just there 3 weeks ago and it was freaking sweet! Chill in/at the pool during the day. And spend all night gambling in their casino. Win some money, then spend it at the spa.
Definitely one of the highlights of my trip to Vietnam and i highly recommend it to anyone wanting to get away from the busy city.
Just remember to book through their casino and not directly through the hotel!
Booking thru the casino allows you to play at the casino and get your room for free!! Free!!
We got upgraded to an executive suite with ocean view free of charge as we checked in on a weekday as they weren't busy.

You will not regret.
TBH, i had a blast staying there for 1 night and checking out a 3pm the next day. 2 full nights may get a bit boring as there really isnt too much to do there.
