Hi, A few weeks ago my family stayed at Rainbow beach Holiday Village http://www.beach-village.com.au/
absolutely terriffic park, we stayed in the chalet cabins right next to the pool. They quite a few cabins but you would need to book soon. This park is in the main st, walk to shops and beach.There is also another park out of town a little
Tin Can bay is not far away, it may have a park, a lot quieter than rainbow beach, each morning dolphins come in for a feed at 8am at the tourist centre.
