Was lucky enough to be visiting on opening day (Saturday). The queue line was, as previously stated, amazing, and the building from the outside was absolutely breathtaking and rivaled that of poseidon in my opinion. The ride itself was very enjoyable, the screens were high quality, the seats were comfortable and well synced, and the air effects were very convincing. My one complaint would be that its too short, lasting around 3 minutes, which is less than pretty much all other dedicated dark rides in the park. Nevertheless, definitely worth riding and it was very cool being in the first hour of opening.
