From the CU website:
"For information on tickets, call the Cornell athletic ticket office at 607-254-BEAR (2327). Tickets for this weekend's games can also be purchased through Ticketmaster (508-931-2000). The Cornell ticket office will receive a limited number of tickets for the regional. Ticket Prices: Individual Day Tickets: $25.00 / All Session Tickets: $50.00"
Posting this again
I posted this on another thread but:
