As a bearded dragon owner, I am definitely puzzled by the decision to drive to the wedding rather than leave her beardie behind. Bearded dragons need a very controlled environment with proper lighting and humidity. They are very hearty and easy to care for in the right environment, so I often have friends petsit for mine without issue. They can literally go weeks without eating (not that I would ever do that), so just having a friend stop by and give my beardie some fresh salad every couple of days is sufficient. All of the lighting can be on a timer to keep the environment where he needs it to be without any intervention from my petsitter. But being out of his temperature/humidity-controlled enclosure for days would be very bad for him. So it seems like a MUCH worse option for CG to have taken her beardie with her on a road trip than to leave him at home and just have someone feed him every few days while she was away.
