Ava's shenanigans with her opportunist friends could've been directed better into more fun and adventurous scenarios instead of the slow paced sequence. The concept of the scheme was a great idea. They could've introduced Ava to actual adventures like cliff diving, surfing, jetskies, yacht stealing, etc. Than just crashing a party. She was deprived of so many experiences. And all she got for the short time was food, swimming, sand, bartending, and a bland ass party. Although not everyone was fond of all those JC crushing moments, it was necessary for Ava to experience that and she get to explore. I also think Jillian and Michael's background a bit blurred.
