Sphere 2025 Questions

Hey guys. Just booked Vegas for 4/16 through 4/19 will be going to the first 2 shows of that run. 2 questions for y'all. Is there going to be a shakedown and if so where do you think it'll be? Where was it last year? Haven't been in Vegas to see the boys since 2017 tour opener. Also ticket prices are pretty high right now. Do you think it's worth grabbing 2 tickets at now around 250-300 a ticket or do you think prices will go down closer to the show? Either way super excited!
