According to the Walt Disney World website, Primeval Whirl is scheduled to open for “seasonal operation” beginning November 24th. The ride will remain open until November 30th, closing again on December 1st.
It’s likely that Disney is opening the attraction for anticipated higher crowds as that timeframe is Thanksgiving week before a typical lull in early December. Of course, with the opening of Rise of the Resistance on December 5th, it’ll be interesting to see if that has an impact on resort-wide attendance during a typically slower time between Thanksgiving and Christmas.
The fact that Disney is going to open the attraction for Thanksgiving shouldn’t come as a surprise, as our latest operational update for the attraction pointed to Thanksgiving as a probable candidate for “seasonal operation”.
