Questions!

Hey guys! I’ll be in Vietnam between 3-4 weeks I know 10 days will be in Ho Chi Minh, 5 days between Hoi An/Da Nang, 1 day in Hue and 6 days in Hanoi and 3 days in Ha Long Bay. Travelling with my partner and was wondering if any locals have suggestions for us, we are big into our food & fashion. She loves skincare so any clinics that do speciality treatment would earn me brownie points please!
