My family of 7 adults will be traveling to Cairns in a couple of weeks. Flying into Cairns. Wish to tour the reef and rainforest, at minimum. Open to other suggestions. Do not plan on renting car. Advice on where to stay or exact tours to take would be greatly appreciated. 5 nights. Scrambling to book accommodations. Should we stick to Cairns or broaden our search to other areas, and if so, how does that impact transportation?
