I will go to Bali in October and join a group for 6 days and 4 nights, including two free days. How much cash do I need to exchange? Do I need both US dollars and Indonesian currency?

I just went there during the summer vacation and the situation was exactly the same as yours. Two days of free time. One day we stayed in a hotel, where eating was quite expensive, and the other day we went to a beach. The tour guide recommended many free water sports, including snorkeling and a submarine ride, which cost 165 US dollars. Usually in this case the tour guide will recommend you where to go.

As for money, 300 US dollars per person is enough. You don’t need to bring Indonesian currency. You can exchange it with the tour guide in RMB when the time comes. You can exchange it in many places.

There are many places in Hong Kong. Disney, Ocean Park, and Madame Tussauds are all good. You can also go shopping in shopping malls to buy famous brands, which are much cheaper than in the mainland!

I hope you will be satisfied with my answer. You can ask more details.
