My wife and I just spent 8 days here, via a deals.com.au voucher.
Wasn't sure what to expect, but was pleasantly surprised. We both enjoyed our stay very much.
I have read some of the other reviews, and I guess some of the negative comments may have validity depending on the circumstances, see below, but we did not find anything negative about the stay.
The hotel itself is lovely, but it is big with lots of marble and fancy furnishings, so it might not suit everyones tastes. Lots of walking if you are in one of the far rooms, as we were.
The beach is great, clean, no hawkers, water seems clean also (swam several times and did not get sick).
The room (Ocean View King) was excellent, very modern, clean, etc. a good size for two people. The only issue I had was that some movies on the interactive tv were only in Vietnamese, without English subtitles (everything is controlled electronically, so you need a degree in IT to work things out :).
The breakfasts were excellent, and we had 3 free 4 course dinners which were of a good standard, with good service by staff. However, if you paid for dinner you would be probably be paying more than in Hoi An. We also bought a seafood bbq one night, which was about $20 each, but good food, and fun as there was a band. But you would want to catch the shuttle to Hoi An for dinner as well, which adds to the variety. Don't forget to book the shuttle bus in advance, otherwise the taxi will cost you extra. It is about 20 minutes each way, so you need to be prepared for a bit of travel time.
We found the staff to be very helpful, and they added much to our stay there. Could not really fault the service.
Wine is a bit expensive perhaps, but it is in most places in Vietnam. Beer was reasonable I thought given the nature of the hotel, but of course you can buy it cheaper in Hoi An if you have dinner there.
Massages were very good, but not cheap perhaps compared to places such as Bali.
Cons. Not really any that we found, but here are some comments. When we went in early June 2013, it was fairly quiet, which was good for us. But if it was busy, with lots of families, it might not be so peaceful, if that is what you want. Many of the families staying appeared to be Vietnamese, so the hotel is not just a resort for 'westerners'. We had no noise problems where our room was situated.
There are some activities to do during the day, but otherwise you need to keep yourself busy. Not that much to do at night, so visits to Hoi An may be needed (which adds to the cost if you can't get on the shuttle).
Marble mountain is just across the road, so you can easily guide yourself there and fill in a hour or two. It was hot when we went, and if you walk up to the top obviously it is harder than catching the escalator (which you pay for). Be careful buying marble stuff in the local shops as I think most of it is over priced, be prepared to bargain, and if you don't really know what you are buying then who knows what the quality is.
We also went on a motorbike tour to My Son. I drove my own bike and my wife went on the back of the guides bike. Bikes are all small, e.g 125cc or so, and everyone drives slowly. My Son is worth a visit, but not as impressive as some other ancient sites in Asia, partly due to bombing in the American war (as it is called). A long day though, and it was pretty hot walking around.
Despite all the warnings I had read on the WWW about driving your own bike, it does not seem to be a problem, as long as you are a reasonable rider and have some common sense. Of course it would be different if you we're in Ho Chi Ming city. In my case I just had to follow the guide. Not sure what the road rules are, you just seem to merge into traffic, and of course it is right hand drive. Did not see one policeman/car the whole time, so not sure if having a licence is an issue or not (I have an Australian one but did not get it endorsed in Vietnam). Nam at http://www.hoianeasyriderstour.com/ was good, although there are several easy riders so not sure how it works. But he was helpful and easy to work with and delivered as promised, and his English was OK. The actual guide on the day was another easy rider but he was a good guide anyway.
A visit to the Lady Buddha at the base of Monkey Mountain is worthwhile, only cost is the cost of the taxi, maybe 550,000vnd return.
Went diving off Ham Island as well. Worth a day trip as there is a boat trip, 2 dives and a great lunch on the island, all for $80. Not world class diving but fun enough if the visibility is ok. Some nice corals and fish, e.g. Lion fish. Went with chamislanddiving.com, who did a good job. Once again there were only a few of us, so it was pretty relaxed, but might be less so of there were 20 divers. On an old converted fishing boat which was fun, if not quaint and slow.
Also went to Ban Na mountain and cable car. About $20 each for the cable car and access, plus taxi, $35, so perhaps not cheap for those on budget, but worth the visit if only for the trip up and the novelty of the resort/theme park at the top. Who would think of building a mini Disney Land on top of a mountain. Don't miss Fantasy Land, if only because it is hard to believe they built it here. Fun for kids if you have any.
Overall, the stay was good value for us, but perhaps partly because 1 Aus$ is 20,000vnd.
If it drops significantly then Vietnam as a whole will be less of a bargain.
Hope this helps.
