As a member of the Big 12, I attended bowls in San Antoinio (great place), San Diego (Wonderful), Dallas (yuck, but great nudie bars), Tempe / Pheonix (not horrible), Jacksonville (not bad...and now it is a Big 10 tie in)...Miami...but that was old Big 8 days..
** The destinations weren't horrible, but in today's world, I would hate being tied into New York City, Memphis, etc......
I would have to say that Pasadena, Orlando, Tampa, Jacksonville, Dallas (?), and Tempe/Pheonix (?) are more attractive for vacation deals, but will say I really wish that the Holiday Bowl was on the table, because San Diego was awesome and I wish the Alamo would have stayed Big12 vs Big 10
** The downfall is that a lot of Big 10 destinations are pretty expensive places to travel in January or late December. I went to San Diego for about 1K less than it was going to cost to go to Orlando or Tampa.... Stupid Mickey Mouse !!
