Hi All,
Just would provide some ideas for your guys and have a safe trip
1) Cost effectiviness on budget airlines: SG->Macau->SG by Air is cheaper then SG->HK->SG
2) Hong Kong includes Hong Kong island, Kowloon Peninsular, N.T. and some islands surrounding Hong Kong. When you talk about "Hong Kong" in Hong Kong, it means Hong Kong ISLAND, but when you talk outside Hong Kong, I think people assume you talk about the Hong Kong Special Administration Region (entire Hong Kong).
3) I saw your route and schedule, please make sure you know where are places are, otherwise you will spend a lot of time and $$ on travelling, e.g. Goldfish/flower market at Prince Edward near MongKok, then you go HK island, then come back to kln again, the MTR price is around HK$13 for across the harbour. So, I would suggest you to stay the whole day in kln and spend another whole day in HK island.
4) The hotel is very convenient at MongKok, but becareful your personal belongs and safety.
5) Macau or Macao will be always slightly higher temperature in summer than HK, and the taxi is much much cheaper, you might feel what is the real "hot" weather which is differnt from Singapore, remember to drink more water and find the toliet, not easy to find sometime. You will find the old building and street are very similar to Malacca.
5) The tape water is not drinkable in HK and Macau, you need to boil it first before drink.
6) If it is possible, go with someone who lived in Macau and HongKong before as a tour guide.
7) Always watch out your belongs.
8) Don't miss out the summer sales in HK during Sept timeframe. The MongKok computer shopping center is very neat your hotel, or you can go Shamshuipo for the Golden Shopping center by MTR, just 2 stops away.
Just my $0.02 idea, good luck and have a happy trip, don't forget to share your pics with us.
