Mia seems to absolutely never be at the beach, is that on purpose?
Edit: Seems to be either deliberate or something you haven't gotten around to.
Also, semi-related, one thing that might make for a good quality of life feature is if you can use your phone to call girls and ask them to join you at a location. For balancing purposes maybe only once per day when their suspicion is low, but it'd be a helpful way to get all the swimsuits, and potentially some future location-specific events.
