From personal experience I can highly recommend Daydream Island. It is such a cute, lovely resort located in the beautiful Whitsundays. It is also very easy to get to. There are two airports you can fly into, the Great Barrier Reef airport on Hamilton Island or the Whitsunday Coast airport on the mainland at Proserpine. Flying into Hamilton Island is more convenient as you can then get a boat transfer to Daydream Island which takes approximately 30 minutes. If you fly into Proserpine, you have to get a coach connection from the airport to Abel Point Marina at Airlie Beach which takes 30 minutes, then connect with a ferry transfer to Daydream Island, allowing another 30 minutes.
I think it is perfect for families! Kids absolutely love all the activiites and they never get bored. There is a daily activities program and every Monday, Wednesday and Friday they feature the latest released movies in a unique open air cinema. For good value food and a great atmosphere I would suggest the Fish Bowl Tavern. Serves food such as steak sandwiches, burgers and chips and nachos. A day trip to the Outer Barrier Reef is also something you should budget for. You will be amazed by its beauty!
Daydream Island Resort and Spa is located in the beautiful Whitsundays and is the perfect island getaway for both families and couples. The resort has a lovely relaxed island feel to it and the staff are very helpful and friendly.

You will never be bored on Daydream Island with so many activities to choose from including a host of free non motorised water equipment including paddle skis, sea kayaks and catamaran sailing. Daydream Island also offers introductory scuba lessons, snorkelling safaris, open water PADI certificate courses, tennis, an open air cinema and so much more. Explore more of the Great Barrier Reef with one of the many Great Barrier Cruises that depart from the island daily (charges apply).
Daydream Island offers a range of eating options to suit all budgets and tastes. I highly recommend the Fish Bowl Tavern which has great food and a really fun atmosphere. There are 3 large outdoor lagoon style swimming pools, kids club, mini golf, pool bars, Day Spa and a gorgeous wedding chapel.
Access to Daydream Island can be by air, road or rail. There are 2 two domestic airports in The Whitsundays, one on Hamilton Island and one on the mainland at Proserpine. From the airports, you can then be transferred across to Daydream Island by boat or helicopter.
