Mention the Nagel-Anderson wedding. Book by May 7th for the wedding group rate. All the rooms are suites and sleep 4-6. Believe it or not, the National Triathlon is in Waco the weekend of the wedding, so book sooner than later! Thanks and gig 'em!
This is usually more expensive than DFW, but it is a hub for Southwest.
If you want to visit the hill country, this would be a great airport to fly into. Austin is on the edge of the hill country and Texas' wine country. Austin is about an hour and a half south of Waco, right down I-35.
