A loose, thin paperboard addition to WDW reservation information we received in the mail today stated, "Be among the first to try MyMagic+. . . This is an exciting time and we hope you'll pardon our "pixie dust" as we make adjustments that come with any new experience. . ." [Emphasis mine.]
Actually we decided to delay our Central Florida vacation about a year to increase the chances that a smooth Fastpass reservation is in place at WDW
so that Universal Orlando's newest Harry Potter stuff is all opened
and the first month (year?) crowds will have thinned out a little.
