Flight
DFW is definitely the closest large airport to all the wedding activities. You can rent a car or take the TEXrail from the airport directly into downtown!
Train
For those of you used to mass transit, or those that want an adventure, the TEXrail will take you directly from the airport to downtown. The downtown area of Ft. Worth is very walkable with a lot of great restaurants and things to see. The venue would be a short Uber/Lyft ride away if you choose not to rent a car!

AirBnb is also a great option. Most of the weekend festivities will be in/near downtown Fort Worth.
