Would you recommend we bring our car over on the ferry if we stay in Friday Harbor? The only time I've been it was for just a day trip and we left our car in Anacortes.
Bring your car over, there are other places on San Juan island other than Friday Harbor.
There is a marina on the opposite side of the island where you can wander. We've stayed at Inn to the Woods twice, the owner is very nice and each room has a hot tub. Not far down the road is an incredible restaurant called Duck Soup Inn. They should be open now, they close during the winter.
There is an alpaca farm we found, never got a chance to stop and check it out though.
