Hello Angel, congratulations on your family's first trip to Disney! I would definitely say, go as soon as possible, only because it's Disney World! I would go tomorrow if I could! If you're not concerned about dinner reservations then it seems as though you really have nothing holding you back to go in August. However, I was planning a trip for Sept. because we got a pin code for free dining, but they are offering free dining in Sept. to everyone (a Disney cast member from their
travel agency confirmed this). But we decided to use our pin code to go in August because Sept didn't work because of DP's work schedule. Maybe we'll see you down there, have so much fun whenever you decide to go! P.S. We went last year Aug 10th-18th, it was hot, but Disney has a lot of inside attractions to cool off. The crowds were high some days, but moderate others and nothing unbearable. Nice swimming weather, too!
