I’ve used Peak 1 Express several times and have always had a positive experience. I even had a last minute cancellation (literally several minutes before I was scheduled to take the shared shuttle) because I was able to share a ride with a friend, and when I was expecting to give up my money because of such late notice, they actually gave me a credit for another shuttle!
My latest ride with Peak 1 Express was from DIA to Breckenridge and the first part of the shuttle (DIA to Frisco) was with Jay and I give the experience 5 stars for his courtesy and entertaining facts that he shared throughout the journey.
I removed one star from the review because for the second part of the journey from Frisco to Breckenridge our driver (a different driver than Jay) was soliciting reviews, telling us about the perks that they receive from the business for good reviews. I felt uncomfortable in this situation, but otherwise the driver was friendly and the rest of the ride went smoothly.
