About Beach Vacation: it’s a quite simple game. You have some options to look for and talk to the girls. There are three main female characters: Lucy, Milena and Maela (Milena’s mother). Besides some secret scenes. The main character is Floyd. The story of this game is unrelated to Solvalley School, but I have made some mentions to those who know the characters.
