This Summer, We've Planned To Visit Hong Kong Again (we did 3 years ago, we didn't do much back then, no real plans whatsoever), Just Wanted Some good ideas On Where We Should Go..

If you like hot weather,you could visit to Hawaii.
If you like cool weather,you could visit to Australia.

If you are talking about places to visit in Hong Kong, you can visit Disney Land, OCean Park, Victoria Peak, Victoria Harbor then you could head to Shanghai which is a train away from HK.

you can also visit HK museum of art, lantau island, water world, middle kingdom, central district, lamma island, 10,000 budhas monastery
