First, the customer service from Colorado Sightseer was phenomenal! I got a phone call when our tour guide was running late, which made me feel more at ease about booking through CS.
Will was our tour guide, and he was amazing. Knowledgeable, funny, and experienced. He made sure that all of the people on our tour got what they wanted from their day. Will also made sure that the members of our group felt comfortable around one another. He offered suggestions of things to see and do at each stop.
Each stop along the tour offered different views and experiences - Breckenridge had a lot of walking and shopping, Loveland Pass had incredible views. Definitely bring a camera - the views are incredible.
