Travelling to Australia?

On two day stopovers, like in Hong Kong, are any meals included in the price?

depends on which airline you are travelling

ring the airline your travelling with and ask.

First of all your question is not clear ! you have mentioned stopovers.All International Airlines provide meals on flights. You can give your preference also. But better check up with the airline your booked with.

Not normally... you might find some hotels give you a free breakfast, but usually for lunch and dinner you're on your own.

I wouldn't worry too much about Hong Kong though, food there can be very cheap (or very expensive), depending on where you go...
