I have now sorted accommodation and flights - I am assuming that a car will be useful??? - the cost of just getting too and from the airport seems to be about 2/3 of a hire car. We have 3 full days there not including day of wedding - any things must do with a 2 and 4 year old (we will do the train and sky rail at Kuranda one day - as DS and I are train lovers - and DH and I did it years ago and loved it).
