Gold Coast, HK Park, HK Bontanical & Zoological Garden, Ma On Shan Park (亦可去馬安山廣場的商場消費換票騎旋轉木馬, 好似以前荔園的) also Deep Water Bay, Cyberport and indoor playgrounds of LCSD,
Because my hubby travels a lot, so I haven't taken Adrian to lot of places....we've been to Stanley market, Ocean Park, beaches, HK garden, Victoria park.
I will take Rebecca's advise and planning to visit Ma On Shan park or Cyberport on Adrian's birthday.
Actually, there is a platform garden between the hotel and the shopping arcade. You need to walk up towards the hotel not on the ground floor. It's not a big place but very spacious with "nothing". No playground or so. However, it's worth to go for a walk as there is an area like Singapore so much. By the way, the greenery nearby the waterfront is still under construction.
