when my wife and i went in 2018 we got tickets from a scalper and paid $250/seat to see ISU vs Illinois.
talking to people in Maui that week it sounded like 2018 was a very well attended tournament given the rabid fanbases in the field. Duke, Gonzaga, Arizona, Illinois, SDSU, ISU, Xavier, Auburn were all in participating and save for Auburn, all those programs have fanbases that LOVE their bball program.
2024 the teams attending are Colorado, UCONN, Dayton, ISU, Memphis, Michigan St, UNC and TBD SEC team. UNC, MSU, UCONN and ISU will show out very well. Dayton and Memphis probably. Colorado probably the "weakest" fanbase
Duke fans were spending crazy amounts of money on tickets.
