Hotel
If you would like to stay in downtown OKC, this is a good option. This is where the reception is being held, and we have reserved a discounted block of rooms for anyone interested in staying there. The hotel hasn’t provided a booking discount code, but has provided the specific link (https://reservations.travelclick.com/13987?groupID=2711160) for booking. If you'd like to call for your reservation, you should be able to tell them you are wanting to book a room as part of the block reserved for the Gillock wedding. This hotel is in downtown near the Myriad Gardens, has a shuttle to Bricktown, and is also adjacent to OKC's new streetcar system. It's a beautiful older building (built in 1909) that was renovated and opened as a hotel in 2006. Restaurants in the hotel include Flint (off the main lobby) and Vast (the hotel is connected to the Devon Tower, and Vast is located on the 49th & 50th floors of the Devon building).
Flight
This is the most convenient airport to fly into/out of. However, there is also an airport in Stillwater (if you're with Kelley's family) or Tulsa (if you're with Nathan's family). OKC will be closest to the ceremony/reception sites.
