If you're going to beach it "China Beach" (My Khe beach) is picturesque. Just up from Da Nang. Touristy and fun. Surf is normal, Decent left right beach break, lots of the accoutrements of beach life. You n the missus can just chill out and drink and eat.
I'm liking the sound of that fella. The missus is worried I'll try to take her upriver about 75 clicks above the Do Lung Bridge etc. I want to be within chucking out distance of a good bar at all times
