Whidbey is about 70 miles from everett, but there are places like mt vernon that are more in the middle that would work for meetings.
Bremerton is the same distance from whidbey but you have to hope a ferry to get there, but so do I do get there. Bremerton with the ferry is almost 2 hours for me, but most of that is wait time and ****, the drive is actually fairly short.
