I remember this a kid. I recall possibly they arrived to a home/hotel during a storm and were unable to leave. And inside this place was something weird at every turn and they became more intense. One scene sticks out. There was a stage, no audience just one or two people. A curtain was pulled. And there was a moving theater, water and a boat, and a fake sea monster coming up. All these were built into the stage. Water was also splashing out of the moving animatronic theater.
