Flight
DIA is the best airport to fly in and out of. Windsor is about an hour from DIA, so keep that in mind for transportation.
Travel Note
Zach and Katie live in Fort Collins, but the wedding is in a nearby town called Windsor. There's a lot more to do around the Fort Collins area than the Windsor area if you're interested in staying around there! Fort Collins is about a 20 minute drive away from the wedding.
