vietnam tet season

hi everyone! i’m traveling to vietnam from dates jan 27 (9 pm arrival) until feb 4 (12:30 am departure) of next year.

jan 27 - 30: HCM

jan 30 - 31: FLIGHT HCM - HUE in the afternoon and stay overnight in Hue.

jan 31: HUE - DA NANG and HOI AN via Hai Van Pass in the afternoon.

jan 31 - feb 3: DA NANG and HOI AN

feb 3: AFTERNOON FLIGHT TO HCM FOR DEPARTURE BACK IN MNL

i know it’s tet season but is my plan doable on the said dates? and am i making the most out of my time? lastly, will i still be able to shop for souvenirs on hcm on my last day?

your kind suggestions and tips to a more tourist-friendly itinerary will be appreciated. thank you so much po!
