suggested 4 day itinerary

hi there, thanks for the replies!
we have came up with a few alternatives for our itinerary, hopefully you guys can give your opinion about which on is better!
14th may: arrival in perth at 12am (not sure what to do yet, to wait in airport or???)
14th may morning: check into settlers' rest, tour swan valley (i'm not sure what activities are included in the package for settlers' rest)
15th may morning: check out of settlers' rest, day tour of boshack
16th: fremantle
17th: city tour
OR
14th: boshack day tour, then check into a park (are there any family parks that we can stay in?)
15th: tour swan valley, check into settlers'
16th: check out of settlers at 11am, fremantle
17th: city tour
we decided to do a farm stay at settlers' instead as the 1 night farm stay at boshack is quite expensive for us at $189 per person, with everything included though. but the activities at boshack are very attractive and so we decided to do a day tour there, which is at about $65. we will be driving. i am more inclined to option 1. what do you guys think??
