Unfortunately I've never had the chance to travel in Vietnam other than arriving at the Ho Chi Minh airport and taking the public bus to the Cambodian border. I once took my Cambodian family to Ha Tien so they could get their first stamps on their passports, but we do hope to travel there as a family one day.
Of course we'll have to wait until the world returns to normal, still stranded in Suriname for now. Thanks for sharing this with us @trangbaby.
