5. Do not neglect reserving FastPass+ times.
Yes, you have a large group, and if you’re hoping to experience the parks together for the most part, you need to be sure to make the most of your FastPass+ selections each day. If you’re staying on Disney property, you can do this 60 days in advance. If you’re staying off property, you can still reserve FastPass+ times 30 days in advance. Neglecting to do this—especially during peak season—will almost certainly land you and your large group in very long stand-by lines, which will almost certainly create havoc for your group. This is especially true if there are small children in your traveling party.
