Disney is extending the refurbishments on both Magic Kingdom's Astro Orbiter and Disney California Adventure's Red Car Trolly.
Guests can expect Astro Orbiter, which went down unexpectedly in mid-July, to come back online on September 19th.
As for the Red Car Trolly, which was expected to reopen early next year, Disney hasn't provided a date for reopening, instead listing the attraction as closed through 12/13/2020. Guests shouldn't worry though, as that's the date Disney gives most refurbishments extending into a new year without a firmly set reopening date. Some guests expect the attraction to reopen with the upcoming Marvel Themed Land, although there is no evidence to support this theory.
