Just did the same exact thing. Thank you for sharing this information. It was a little disheartening to learn June was sold out (we're going June 2nd). Hoping, like you said, that these are legit and there are no issues. Site says you can refund any time before the date of usage so there is that, at least.
This trip is gonna be super somber and exciting at the same time. The day before, we are saying our goodbyes to Muppet*Vision 3D, DINOSAUR/Dinoland USA, Tom Sawyer's Island/Rivers of America and WDW (god their decision-making has been sucking so much a** lately). Then the next day, we get to say hello to something brand new and exciting in Epic Universe. I am unreasonably hyped for Dark Universe and Starfall Racers.
