I booked this tour so that my wife would have a 'cuddle a koala' experience. We were not told that we had to book! When we joined the queue we were too late. The tour was otherwise quite good but I got the impression that the driver was bored.
Our guide was great. The bus tour and riverboat tour were good with lots of good info and sights. The koala sanctuary was good but we were disappointed in not being able to hold a koala. You have to get there early to get a ticket to hold one only so many per dayand they had already given them all out. I would suggest doing that earlier in the day, or the guide get them in advance-at least for the people who have rebooked.
