This website sells accommodation packages in resorts around Australia, New Zealand, and other places around the world. It offers great deals for families on a tight budget wanting a resort-style holiday but at a bargain price.
The staff are helpful, friendly and willing to think outside the square to give you a great holiday and they also happily share the pros and cons of different places that they've discovered, for your personal needs. For example - we have three kids including a baby, so they suggested a place with lifts that was close to parks and calm beaches on the Gold Coast. They made sure we would have everything we needed with the minimum amount of stress to deal with.)
Wait until the last possible moment to make the booking - the closer it gets to the check-in date, the cheaper the price. If you are simply wanting a bargain holiday, tell them your budget (and your destination if you know it) and leave it in their capable hands to get you the best deal without missing out (kind of like a mystery holiday). Usually the best specials become available from Wednesday but there are good deals available all the time and you just have to tell them what you want and they will do their best to get you something suitable.
