dramatic picture to give you the point...HA!
My Best advice for beating some of the hottest parts of the day is morning touring. Get your buns out that room as early as possible and get to the parks. Do all running from ride to ride then. Get on as many as your "must do's" by 1pm and then get the heck out of there!
Morning touring is not for shows, or attractions that don't have any outside queue at all. Get those done in the evenings when the sun has gone down for the day. Walk through the gifts shops when you can - that cold air will feel like a kiss from heaven.
So, that's my take on beating the heat. Are you thinking about going in the hot months? Email me. I would love to book your Summer trip and give you a touring plan that will keep you out of the worse of it! Take it from me! I did August 5 years straight! Dana@Mouseketrips.com
