I just figure that if I am going to spend thousands of dollars on my vacation, I am not about to lug around water all day long to save $2.75. When I get thirsty I buy a bottle of water and move on. When I figure what I have already spent, it's just chump change to me. I budget it before the trip and am able to go to the parks with no back packs, extra cups or anything that doesn't just fit in my pockets. I believe that life simplicity is worth something. I also am not going to go into pay as you go dining places and beg for free water. Just how I was brought up I guess, right or wrong.
