Entire family vacation

Really depends on the type of people you are.... City folk or country folk ?
I myself like camping or some type of outdoor vacation ( skiing , boating etc)
but others prefer to be in a hotel somewhere.
You could rent a big houseboat on a beautiful lake . The kids could fish and swim , maybe get some jet skiis ,
Catering is often available.
White water rafting is a big deal out here . Check out Mackay Bar River trips . Trips down the Salmon River through wilderness that are fully catered and an experience of a life time ! People come from all over the world. And 30k is about right...lol
