Travel
The closest airport would be Denver International Airport. DIA is a hub for both United and Frontier Airlines, so those would be the flights with the most frequent arrivals. Obviously, DIA serves a ton of other airlines.
Here's a link to car rental options at the airport: https://www.flydenver.com/parking_transit/car-rentals
They do Uber, Lyft, and tons of other shuttles as well.
We don't have any specific hotel blocks reserved but we can add a number of options of where to stay below. PLEASE NOTE Lafayette (where we are hosting the party) is the neighboring city to both Louisville and Superior, where the Marshall Fire has affected hotels. PLEASE keep an eye out for any hotels you are looking at independently in both LOUSIVILLE and SUPERIOR. In general, and again for those who want to research independent of the forthcoming list, other neighboring cities would include Denver, Boulder, Broomfield, Westminster, Thornton.
