THON announced a major change yesterday: For THON 2015, only three floor passes will be distributed to each family for the Sunday of THON Weekend, changing the PASS system utilized by Four Diamonds Families.

Family Relations Overall Cara Wojciechowski announced the shake-up in an email sent to Four Diamonds Families. She wrote that the three-pass distribution applies for “the entirety of Sunday, from 8 a.m. to 4 p.m., not Friday or Saturday of THON Weekend.”

“After hearing your feedback, we believe this solution to floor capacity is the best decision possible to continue to include all families in every aspect of THON Weekend,” Wojciechowski wrote. The email cites safety concerns as a top priority and primary reason for the switch.

In layman’s terms, only three people from each family will be allowed to be on the floor at THON during Family Hour, including the Four Diamonds Child, instead of the child’s immediate family like in years past. The family’s passholders will also have to stay on the floor for the final six hours of THON, essentially not being able to swap out their three passes throughout Sunday. For those unable to use the three passes, THON will be creating a Family Section in the stands to give them a place to stay Sunday.

We’ve reached out to THON for a comment on the change and will update when we receive a response. The email also said that more details about the switch to the floor policy will come as THON gets closer.
