On the bright side, though, you’ll have plenty of company, the parks are guaranteed to be open late, and as many rides as possible will be up and running. Keep in mind, though, that Florida Department of Health regulations prohibit Disney’s Culinary Cast Members from preparing, or even handling, foods brought in by guests. If your schedule allows any flexibility at all, you should avoid these peak periods. Be aware, however, during the periods of mid-December to February, mid-June to July, during the first 2-3 weeks of October, and on Thanksgiving Day (in some cases), tour groups from South American countries, mainly from Brazil and Argentina, will invade Walt Disney World and other Orlando theme parks.
