I just came back from this hotel.
Excellent!
The room is big, clean and nice. My kids like playing with the electrical curtain inside the bathroom next to the private small hot spring tub.
The Japanese buffet dinner is excellent, there are so many sashimi, many of them I have never tried in HK.
On the last day morning, I took the kids to the swimming pool and spa, then we leave hotel at 12:30pm. We took a taxi to the airport, NT$500.
Just a note!
The Homee Kitchen (the only restaurant at Tai Chung Airport) outside immigration is horrible, there are a lot of fries ! But after go through immigration, I saw another Homee Kitchen inside which is much better. Also there is another shop selling meat floss (pork) which is cheap, around HK$55 per can.
