I haven't tried to do this for finals but I have successfully done this in the past for matches up to the round of 16 - either the day before, or on the morning of the day you want to go, check Ticketmaster because often there are corporate seats available which are returned tickets. You pay about $100 and get to sit in a fantastic spot, a few rows behind where they often show Rod Laver sitting when he's watching. No food or beverage entitlements included, but an absolutely stellar view plus good celebrity spotting.
I guess some have more cash to burn than others
Small business owners who normally work 6 days per week in a service industry and booked their flights and hotel room on points, is that what you mean?
