Maui Invitational questions

I am trying to surprise my father with a trip to the invitational this year as the cougs are in it for the first time ever.... and more than likely the only time in his life(he's 71) I went through a travel agent for everything so far except the tickets. I simply want to know what the chances are that there are tickets left(even if they're GA...idc where I just want us to be in the gym) when they "ticket only packages" go on sale in August?
