Hello, I am in the very early days of planning our trip to Australia (April/May time). We would love to visit Adelaide and KI. At the moment I am planning a night or two in Adelaide before and after our trip to KI and I am looking at the 2 day excursions to KI. But I was wondering what we would do with our luggage when we go to KI - would we a) take the whole suitcase with us to KI (although that would cut out the flying option as it would weigh more than 15kg) b) leave the suitcase at our hotel (if they allowed this) and just take an overnight bag or c) book a hotel for the entire duration in Adelaide even though we wouldn't sleep in the room for one night so we could leave our suitcase there and again just take an overnight bag.
I would be grateful for any thoughts or suggestions anyone might have. Many thanks. I last visited Australia in 1995 but sadly didn't get to Adelaide!
