Flight
Denver International Airport (DIA) is the closest airport to Boulder. From there you can rent a car or take a Lyft/Uber. Note that to get around to any activities you'd like to do (hikes, sightseeing, etc) it may make the most sense to rent a car as the Denver/Boulder metro area is pretty spread out. There is also an option to take a bus from teh Airport to downtown Boulder. Click the link for the AB bus schedule. rtd-denver.com/app/route/AB/schedule

We have a room rate locked in with Marriott to keep a stable price regardless of other events that may be happening at the same time.
