If you're flying into Colorado from out of town the Colorado Springs airport will be the closest. You can fly into Denver but it is about an hour and a half away just for planning purposes.
Colorado Springs has a lot of airbnb, hotel, and other options for being able to stay. The venue is in Black Forest which is right in/near Colorado Springs as well.
Colorado Springs uses both Lyft & Uber if you'd like those services. We suggest prescheduling pick up rides from the venue given it's location as well in Black Forest. The reception will end at 11pm. A rental car is also helpful to get around the town and visit other parts of it.
