O'Gills is going to be about the only possibility, as PPs have noted, but all of the games are CBS or Turner cable properties (TBS, TruTV and TNT) and I have no idea if Disney will run those stations. It's definitely a weird situation. If they were on ESPN, you definitely would be seeing them all over.
We've cruised during the tournament before (2012 or 2014??) and they had the games on in O'Gills and on funnel vision. At least when we were on it was final 4 weekend - so those games (and the final) were definitely on funnel vision.
