I've said it before and I'll say it again, unlimited days off (or "open") and zero days off are identical. If you have unlimited vacation people are inclined to take less and people respect the vacation you take less ("as you can always take more!"). Here's a study[0] (PDF) called "Overwhelmed America: Why Don’t We Use Our Earned Leave?" It is biased (travel association) but interesting nonetheless. According to this…

It made it less stressful and, coincidentally, could de-stress faster in my vacay than I did when I had limited PTO.
