Or just live in Southern California where the weather is always beautiful and the market closes at 1 pm, so you can spend the afternoon at the beach. (Only problem is that you have to start at 6:30 am).
To answer your question, I don't take much time off because I actually like to trade and am happy to be doing that part of most days. Since I do live in Southern CA, I have most of the day free to do what I want anyway. Trading until 1 pm and doing what I want the rest of the day feels like vacation to me. If the market was open more hours and more days, I would probably take more vacations.
