Yeah Port Douglas offers a lot for you and the kids. Stacks of self contained apartments and kid friendly restaurants (much to the 'dinks' disgust). Attractions are many and vary a lot in price. Heaps of websites with info and there is a new www.facebook.com/portdouglas site which is wanting new visitors so maybe check them out about 8 years ago
Port Douglas is a fantastic getaway spot, with or without kids, heaps to do and it is just such a pleasant laid back town.
I can highly recommend Mantra Portsea for accommodation. I stayed there last year and thought the accommodation was great, spacious and clean. Very pleasant pool and surroundings, ideal for kids. Bus outside door, or easy 15 min flat walk into Port Douglas. Magnificent Beach 2 mins outside back door. about 8 years ago
I loved Port Douglas when I stayed in 2006 - so much so we ended up changing our return tickets so we could go back. We stayed in a few places, but I really liked http://www.nautilusaccom.com/index.htm as the owners were really nice and helpful and the apartments were very clean. Its probably a 10/15 minutes walk along Davidson to get to the top end of town.
The Nautilus is right opposite Four Mile Beach and has its own smallish pool.
For things to do, we did a lot of sea fishing with http://www.mvnorseman.com.au/ captained by Steve and they were fantastic. They always found fish, and the boat is well equipped so that everyone can enjoy it.
For trips, we liked http://www.crocodileadventures.com/intro.htm which is a crocodile place - might not be everyones cup of tea; we loved the drive and the experience of the Daintree Rainforest http://www.daintreecoast.com/; the Great Barrier Reef is easily accessible and great for snorkelling and diving if you are able. We liked going to different beaches such as Yorkeys Knob and Trinity Beach, but watch out for the crocs and the jelly fish. Mossman Gorge is great and you should drive up into the Tablelands for a different perspective.
I like Palm Cove, but its a tad chi-chi, although the pier there is great for fishing from and there are some public BBQs right next to the sea, as well as an enclosed jelly-fish free swimming bit in the sea. about 8 years ago
Mission Beach is a lovely location. It still has a village feel and quality restaurants, beautiful beaches and even shopping. There is a lovely property called Cassawong Cottages in Wongaling Beach (one of the four villages of Mission Beach) which is set up with families in mind. Give them a try. Call the Mission Beach Visitor Centre for their contact details: 0740689873. Enjoy! Sue about 8 years ago
