Heading to Vietnam in a couple of weeks for 2 weeks. Plan is HCM 3 nights, fly to Da Nang and have 4 nights between there and Hoi An, fly to Da Lat for a couple of nights, bus to Mui Ne for 3 nights then back to HCM by bus. My question is how would you split the time between Da Nang and Hoi An? Looking for sightseeing and beach life (weather permitting). Would quality of beaches be better in Da Nang?
