BYOW (Bring Your Own Water) There are plenty of spots inside a theme park to find water (some even hand out free ice water if you ask nicely), but it's more convenient to bring your own. This Mickey Mouse Repeatables Roll-Up Water Bottle ($23) is reusable and portable, so it's easy to bring with you around the park.
