Plot hole: In the scene when Ryan is desperately looking for Maggie; he is running down a corridor. Then Ashley opens her bedroom door and grabs Ryan. If you remember in the last scene, Ashley fell into the water and was drenched and within minutes she is completely dry.
In the scene at the carnival, Ryan hands Ashley a drink that he just bought. The drink is full to the top with ice and a lemon. Before Ashley even drinks any of the drink, she walks over to a carnival ride and you can see that her cup is empty.
