SOLVED. YA, working in her family's resort with her boyfriend, returning guest causes trouble [s]

[Moira]

Okay the name of this book has been driving me mad, and I know when I remember it I will probably kick myself! So I pretty much remember everything but the title and author!! The female protag is working in her family's resort for the summer with her boyfriend. Her family don't approve of him, says he's a bad influence. It's a very prestigious resort where the wealthy come. A returning guest of an affluent family cause trouble between them. I think the previous summer they had flirted with each other. As you can imagine trouble ensues, and I remember at one stage the guest takes the blame for something that happened that would have gotten her in serious trouble!!
Pleeeeeeease help!:)
