We loved this tour. We were blessed with great weather the whole time we were in Seattle area, and the day we went to Mr. Rainier did not disappoint. Shannon our tour guide was the best, very friendly and laid back, we did not feel stressed about the time we spent at each stop. We stopped at one place and the birds were eating out of peoples hands, so I was going to run back to the bus and get some crackers that I brought, but Shannon said no, I have some bird seeds with me, and let us all feed the birds and let us have the time to capture the pictures. Shannon has a love for nature and you could tell she enjoyed sharing it with us. While it's true you could drive up the the mountain yourself, let me tell you the stress free tour is the way to go, Shannon knew where the overlooks were and where to park, all the things you would have had to figure out for yourself and possibly missed. We went during the week and with the covid restrictions I'm sure the crowds were less, but still parking must be a beast on a busy sunny day like we had. The only complaint, was that our hotel was not on the downtown on the pick up list, so we sent a message to our Viator rep and was told that we could park at the Mopop or the airport, we knew the parking downtown would be a bit more, but decided this would be best for us location wise for pick up and drop off, unfortunately we park in a lot with a 10 hour max (did not realize this, just thought we were paying for all day) and came back to find a $70 ticket on our windshield. This was our fault but, as we did ask for parking recommendations prior to the tour, and as we were visitors to the area, it would have been nice to been given better tips about where and where not to park.
