We did it from 9:00 - 11:00 AM on Saturday 12 May 2017. It was fantastic. There were not a lot of people there and we got to ride both attractions. BTW the Flight of the Avatar ride is Wicked Awesome! They offered us a fast past for the ride when we went thru the entrance to Pandora. If they offer one to you take it. We got lucky because we had a trip planned for the date that was offered when they sent the email out in March. It was a nice perk of being a DVC member.
