Ppl o Adelaide . Need your HELP !

Hello friends ,

If you live in Adelaide or know about it , I would like to ask you about some recommendations!

First - If a family coming for a visit what is the best place that is family friendly they can stay at ? I mean a hotel or something . for example in London there was Chessington Safari Hotel was sooo children friendly

so is there something like that and of course to be not expensive ?

Another thing .
If u live in Adelaide and you r such an expert there I would love to have a chat with you for more details about the City ..

Thanks a lot in advance !
