We just had a short local holiday there. In short, when you got only two days of holiday and you don't want to travel far away, finding a good local hotel might be a good option.
Near this hotel we have a beach, the water was no good in quality but if you're parents and you will know that all the kids wanted would be a beach so that they can play around the sand, digging here or there and building sand castle, etc. Therefore, there's no problem for the relatively bad water. Anyway, people still swim there but it's not recommended.
The food is nice, the restaurant was a small one but the variety and the quality of food is superb, they keep re-filling and changing food all night, even during the last half-an-hour. The price is cheaper than outside given similar quality, it is especially true if you go for their promotional packages during holidays.
The guest rooms are big in the standard of Hong Kong, and the view outside is unique and good. The swimming pool is nice and clean, with some toys so that your kids would enjoy. Finally, there are two playing rooms for the kids where you can find video games, indoor playing equipments, chess, boardgames, etc.
It's just wonderful to stay there for one night, simple and relaxing.
