Recommended airports if you are flying in: Easterwood Airport (CLL) in College Station,TX. IAH in Houston,TX, or Austin-Bergstrom International Airport in Austin, TX.
Caldwell, TX is a very small town located between the major cities of Houston and Austin. The Houston and Austin airports are about 1.5-2 hours from where the reception will take place.
We currently live in Bryan, TX which is about 40 minutes from Caldwell. There is a small local airport here Easterwood Airport (College Station, TX) that flies into Dallas that is also an option to fly into if you are okay with a layover.
A car rental will be a must since there is very little chance of Ubers/Lyft in Caldwell.
Hotel:
We recommend getting a hotel in Bryan, TX or College Station, TX. There are not many options in Caldwell. We will update here if we get a block in a certain hotel!
