I think if Tenn. qualifies for the tournament that seats will become difficult to get that third parties will be getting premiums over face value (prices are high already on such sites now). Traditionally, good seats have become available at good pricing after two teams lose in the Semi-Final game. That is unlikely to be true if Tenn. makes the final. If Tenn. does lose or does not make the tournament then it should become possible to buy from fans not coming to the Final or just move into empty seats. Additionally, the UConn section sometimes is not filled and it has been possible to get into that section after the game has started and sit with that group. So, just having any ticket might get you a better seat.
I think you both should be prepared to hit the NCCA link for tickets at 10:58 and continually refresh the page until the site goes "live." All lower level seats I think will gone. There is a level between the lower and upper level that if you see seating available you should take them. You will have to decide about the third level, but the experience at a Final Four is wonderful experience for a fan.
If you signed up for notification from the NCAA they should contact you. I would monitor the official site to be sure (
www.ncaa.com/womensfinalfour).
The only way to get the pre-sale is buy tickets this year and then the NCAA will probably notify you next year.
Another risky action is to wait until UConn officially qualifies and then see if a season ticket holder will order tickets only for you. Those would be very nice seats though.
It is good that you have your hotel reservations as it seems Nashville is popular and very pricey in the downtown area near Bridgestone Arena.
Good luck!
