I’m having the same issue for 8/10-8/20. I’ve seen posts in other forums of this being a common issue for Savi’s and some of the other Enchanting Extras reservations.
Not sure if this has been covered before, but Macao has a gondola system at Wynn Palace. It has themed towers, audio and air conditioning.
