Hi Masaki!

Will Marika be coming on the trip? If so, I'd suggest staying around Pacific Place on Hong Kong Island. Kowloon side is simply much more crowded (buildings and people) and I'm less inclined to stay there. I've stayed at all three hotels adjoining the complex - Shangri-La, Conrad and JW Marriott. They are very comfortable, with the nod going to the Shangri-La.

There's a lovely outdoor park very close to Pacific Place. Within Pacific Place, there's ample space for her to burn off some energy. I believe all three hotels have pools so she can enjoy playing in the water.

The Mandarin Oriental is a lovely hotel, too, but is in the middle of a business block. Here's a link that shows you the relative location of the hotels. It's closer to the Star Ferry if you want to get over to Kowloon to enjoy the sights there.
