We are planning our US holiday for July and are debating whether to drive from San Fran to Seattle over a period of 10 days. As we have 2 boys, 7 and 4, we would need to break the trip with kid highlights so as to not boring them to tears. Apart from the Redwoods (which will excite us but perhaps not the children), what other options are there in Oregon for kids activities?? We plan to stay at some stage for a 2-3 day break at a lake/forest cabin also. Are there any places that are first rate which may not be fully booked at this stage??
