Raemani helps coordinate everyone’s travel schedule- she can help you see who will be at the airport around the same time so you can share a ride.
Public transportation is not very good in Texas, lol! You would be better off sharing a ride/gas money with someone else who has a car or has rented a car. Shuttles can be just as expensive as a cab, so I would not recommend those either. It would be cheaper to just rent a car for a few days. But send your info to Raemani first, she is great at organizing all that.
