It's a fantastic show that I absolutely don't regret. The arena is located a 10-minute walk from the castle, ideally combine the two, have an early lunch, make a stop at Lawson (on the right) for drinks and snacks on the way: otherwise, you can eat on-site but it's less good and expensive. The guides await you in front of the arena at the entrance of the large university building. You will be given your precious tickets (ouch, the face value hurts), an English audio guide, a map of the venue, and the fight schedule. Brief explanations are given at the introduction, but the guides remain available throughout the match to answer your questions and are charming. We were seated in the last 5 rows of the stands, but you can see very well from everywhere. The 5 hours there fly by. My 12-year-old daughter loved the pre-show shopping, the shaved ice with syrup, the atmosphere in the hall, and following the fights by betting on each player.
