Looking for suggestions for accomidation in Perth. As close to Wanneroo as possible. For the June long weekend.

DD1 has netball at the stadium in Wanneroo all weekend. Happy to drive a few kms, but hoping to be as close as possible. Within 15k I guess. And under $150 a night for 6 if possible... Mum will be with me to help control the kids, so can't tent this one

Would much rather leave the younger 3 with her She won't be in it!
