The San Juans are nice, but there isn't much mileage to be covered considering you have eight days. The two biggest islands, Orcas and San Juan, can be completely covered by bike in a few hours each. If you are content to find a nice spot to just sit around and relax in for a few days, it could be a good trip. Or as part of your trip, spend a day riding Whidbey Is. and another day riding around rural Skagit County, both of which have very nice back roads and are adjacent to the San Juans.
