We recommend booking all flights into DIA. There are several options for transportation from there to your lodging, including Lyft/Uber, taxis, and rental cars. Lyft and Uber are generally available at all hours.
While we do not have a room block at the Claret Hotel, it is a great option for those looking for a more elevated or luxury stay in the Denver Metro area.
There are several other hotels in the Denver Metro area, in addition to our room block, if you are looking for alternatives. We highly recommend booking as far in advance as possible as this is a very busy time in Colorado.
There are many great Airbnb/VRBO options in Castle Rock/South Denver that can accommodate parties of various sizes. We highly recommend you look into these options for larger groups looking to stay together or for lodging closer to the venue.
