We have two holes where there is two separate tee boxes , #1 (a par 5) and #17 (a par 3). It's set up so there are five different tee boxes (on most of the other holes, there are 4 tee boxes - some of the par threes have only three distinct tee boxes), and on the scorecard it shows the regular tees with two different yardages (so those tees can be up or back). from time to time I have seen the "senior" tees moved back from their normal spot onto that tee box. I can't say I've seen an alternate tee box up a hill.
