They have the normal one (Sunrise), which you could do for under 4k without much issue I think, and then "the Grand" which would run you more (they are right next to each other and share a beach). If you stay at the grand then you can access all the restaurants at Moon Palace Sunrise and the Grand, but cannot access the Grand normally if you are staying at Sunrise. However, you can get day passes to the Grand for free by just listening to their sales pitch. And even if you do not want to do that, there is plenty at Sunrise for five days. You can also just purchase day passes to the Grand if you really want to go do something there like the small water park or one of the specific restaurants.
