When we arrived in the parking lot, we observed a duck boat pulling in. The passengers were waving various items about, and YMCA was blaring from the radio. The driver got up front his seat and he was dancing down the aisle. I immediately thought, this is *not* something I want to do. However, I was with two friends, and there was no turning back. Fast forward to our boat pulling into the lot, and I was waving a rubber duck and screaming, YMCA! It was a blast, and this is coming from somebody who hates cheesy, touristy, crap. It is a must do, especially on your first day in Seattle. The 90 minutes allows you to see all of the sights, and the driver points out the must-sees throughout the city. Not only does the tour inform you of everything Seattle, but it helps to plan out the rest of your visit. Please do this! It is well worth the 30ish dollars.
