HUGE shoutout to our amazing driver, Amanda ❤️ Pickup was conveniently at at Recess Beer Garden in Lohi. She was punctual, friendly, communicative, flexible, and gave super clear instructions throughout the night.
Red Rocks logistics were great: drop-off at the top and pickup in Lower South Lot 2. Amanda gave us her contact # and an exact pin so our whole group could find the bus easily after the show.
This was our second time using 303 Party Bus, and we'd absolutely book with them again and again. Make sure to ask for Amanda as your driver!

Absolutely terrible experience. This company canceled our reservation just one day before a kids’ prom—an event that had been planned well in advance. The lack of professionalism and reliability is beyond disappointing.
What makes it even worse is that while canceling on us, they were reportedly trying to resell the same bus to our group. That kind of behavior shows a complete lack of integrity and respect for customers.
I would not trust this company with any important event. Avoid at all costs.

Amanda made my night a 10/10 experience! She was kind and cared about my group's safety and well-being. We were able to get a 34-person bus for our big group to Red Rocks, everything went smoothly and perfectly.
