I have visited twice in the last eight months.
There are new hotels opening as well as restaurants.
Really nice place to chill out, literally...much cooler then Saigon, getting cheaper all the time. Best diving in the country.
Forget raibow, whacked expensive. Go out with Dive ! Dive ! Dive !
Trekking in National park is very nice, ask for a guide named Miss Vung. Good English and knowledgeable.
