I went on the 2019 trip to Italy. It was clearly expensive: 15 players; all the coaches, most with spouses; many athletic department people, several with spouses; transatlantic airfares for all; high-end hotel rooms in four very expensive cities; meals at pricey restaurants; and a lot of nice "cultural/educational events," i.e. high-end sightseeing. As best I know, the cost of the trip came out of the Athletic Department budget. (NB: I and the other dozen or so fans on the trip paid our own way for everything. Trust me, it was expensive).
