You may want to bring an extra pair of dry socks. As you enter the park through the Front Gate, proceed to the right, instead of the left, to help avoid crowds. Visit major attractions early or later in the day to avoid longer lines in the afternoon. Plan your meals at non-conventional times to help avoid restaurant and food stand lines. Visit roller coasters and other major attractions during traditional meal times to help avoid their longer lines.
Little ones are especially susceptible to the sun.
Apply an adequate amount of sunscreen on your children before you start your day at the park. Pack some moist towelettes or washcloths to wash off sticky hands and faces throughout the day. Before you set out, designate a specific place for family members to meet if they should become separated. Get input from each family member as to what he or she wants to do. Plan your day of activities built in with several breaks.
