Travel Note
You can't go wrong booking a hotel anywhere near Denver, Lone Tree, Castle Rock, or other nearby cities. As long as you stay near I-25 and don't go too far north or too far south, you'll be near the airport and somewhat close to the venue. The venue is about 1 hour south of Denver International Airport, so pick your housing based on what you care to be close to!
Hotel
Here is a hotel that is in between DIA and the wedding venue - about a 25min drive to the venue!
Hotel
Here is a recommendation for a beautiful resort that is a 23 minute drive from the venue. Keep in mind that this resort is SOUTH of the venue, so while it isn't too far, it is in the opposite direction of the airport (about 1hr away from DIA).
