Since you did not supply specific information about your flights (i.e.
arrival and departure times), I can only give you some rough ideas.
These are the places that you want to go:
2. Ocean Park
3. Victoria Peak
4. Ladies' Market
Since you have just 5 nights here, and at most you probably have just half a
day on the first and last days, you really have just 4 full days.
Since you put Disneyland on the top of your list, I assume that it is more
important to your family, so you should spare a good part of a day there,
making sure that you will catch the two main popular events - the parade and
the fireworks. So you should go there for lunch and stay till the
fireworks are over (assuming that they still have daily fireworks in the
The Ocean Park is also a place that you should spare a good part of the day
for. So I would say go there in the morning (according to their website,
they are open 10am - 6pm) and stay till mid afternoon. Your family will
probably be a bit tired after that. Go back to the hotel for a bit of rest
if time allows. Then go for an evening excursion.
There're two evening excursions: the Victoria Peak and the Ladies Market.
You will probably have time for just one each evening (unless you don't like
to shop, in which case Ladies Market will just be a 30 minute walk!) You can
do one in the Ocean Park evening and one on the first evening you arrive -
if you arrive during the day.
The typical way of going to Macau is by hydrofoil. I would suggest not going
on the weekend to avoid the crowds because some people from HK tend to do
that. If you want to just go and look around, I would suggest going in the
morning and come back some time after lunch, giving you still plenty of time
to do stuff in HK - since HK shops tend to open at 11am or later and stay
open till 9pm or later.
As for choosing which day to do what, you should first find out the ticket
availability of Disneyland and Ocean Park because that may be the
determining factor - weekend prices at Disneyland is also a bit higher.
Have a great trip!
