Just enquired with the hotel. Lunch and dinner is a 3 course set menu. Drinks are inclusive all day (not just during meals).
Yes. I checked out some dates mid-week later this month. The price is somewhat more than 8000 Baht. There are two packages. The Diamond package (spa, full board, drinks throughout the day) is more like 11,000 Baht. The full board package with drinks at meals is around 9,000 Baht. Still good value. I'm tempted to book it.
