Our itineary so far:
We're arriving in Hanoi on the 19th of August.
Stay two nights there, before doing a Halong Bay cruise from the 21st to the 22nd.
We would like to visit Hue, Hoi An and Da Nang. We fly back from Da Nang to Hanoi on the 30th.
How many nights should we spend in Hue/Hoi An/Da Nang? We would like to spend some time on the beach. Have also thought about going to Cat Ba for some beach life, but maybe some other beaches closer to Hue/Hoi An/Da Nang will be good enough? As I guess you understand, I'm a bit confused about what to do...
