Gosh, good question! So far I have not seen anything advertised about it. Maybe it would be a good idea to call, 'The Stitchin' Post', to inquire about any shuttle services from Redmond area. I will keep looking and post any new developments for anyone on this posting.
I too will be attending the quilt show this summer for the first time. My two cousins will be joining me! I am really excited about the entire weekend! SEW MUCH FUN!!
