Those are fund-raisers in disguise. Half the final price is skimmed off for
the school's benefit. The rest is shared among the travel agent and the
various service providers the trip involves (transportation, meals,
lodgings, admission fees, whatever else may be part of the package).

University alumni/ae associations do quite a few of these fund-raisers.
