The day we fly to Adelaide, to begin a tour to Kangaroo Is the following morning, we have a choice of the time of day to fly to Adelaide. We could either tour more in Sydney and fly out PM, we already have highlights earlier in the week including Opera House, Bridge, etc and we intend to use our leisure day on the tour for Blue Mtn, or we could transfer to Adelaide early AM and tour Adelaide for the remainder of the day. Which would be best?
