We are flying from California with our 3 grandchildren 8,10,12 to Bellingham. We have never been to Washington and want a fun adventure. Not sure if we should stay in the area or drive to either Seattle or Vancouver, Canada to see the sights! We have been to Vancouver before and love Stanley Park and the suspension bridge. Looking for suggestions such as ferry trips, Space Needle, etc. Should we go South or North ( don't really have time to do both), rent a house on one of the islands or just hotel it? Traveling in the next 3 weeks so any so we desperately need help. This is our 1st trip with just our grandkids and want it to be one that they remember. Thanks in advance for any suggestions!
