Once you have decided what town you will stay in on Phillip Island, you need to find 3 possible accommodation options for your party of 5 for 2 nights. Make sure that you get a price for the total number of rooms and nights you will be staying. You will need to look at an online booking site (E.g. www.booking.com ) and screenshot the information for each option.
Once you have done this, choose your preferred option and give a reason why you choose that one.
