From now on, these guys are my new shuttle service when travel around Colorado. We had a mishap with our luggage while on our way to Breckenridge.  When we realized it, United Airlines called me and explained to me that I had to go back to the airport. Scott, from Summit immediately asked me if he could speak to the rep.

Long story short, Scott tried to explain to the rep that they can go back to the airport and pick up our luggage...they've done it before for customers in the past.  Unfortunately, United couldn't give us a straight answer, so my friend and I had to make the 2 hour drive back to Denver.

Either way, Summit and Scott were amazing. They gave us a great rate to go back to the airport and back to Breckenridge.

Go with Summit if you plan to make trips around Colorado. I highly recommend them.
