You know this is fascinating about the rental car. Normally it's horrible taking a car to anything, but I guess in this case so few people had cars that it was just easy? Did you literally just park in the little parking lot outside the Honda Center? Or across the street from it?
I decided not to fight for the buses, and paid for Uber. Which was fine on the way in.... they insisted on Ubers having to drop off at the transport center several blocks away, so I said screw that and set my destination as the hotel across the street from the Honda Center. LOL. Worked fine. The REAL problem was leaving. Walked across to same hotel to call a ride. Uber and Lyft basically were overloaded so badly that I was getting timeouts, etc. Then drivers were calling off when they saw where the pickup was, etc. I think the second night I gave up and went to a nearby place in the shopping center to chill for a bit before ride-share recovered.
So yeah... I'd totally be willing to rent a car to avoid all that... eating the parking costs and rental fees might still not be much more than the Uber costs from/to airport and from/to Honda three times.
