When we were deciding between the Olympic and Mount Rainier day trips, our fellow travelers shared that Mount Rainier was more worthwhile. The whole trip was great, with only one minor drawback: KKday didn't seem to provide us with the tour guide's contact information the day before. We were supposed to meet at the Central Library at 8:10 am, but we arrived early and had no way to contact the guide. We finally met the guide at 8:40 am.
I chose the Space Needle, Chihuly Gardens of Glass, and a boat tour. The whole trip went very smoothly, and I really enjoyed it!
