I would say Holiday romances are in the majority of cases, just that, a holiday romance,
Laura will be well used to all the attention Shane and will play the game to suit herself, as I imagine most people do in that position. Young, and to an extent free and single away from home in the sunshine.
If you feel you need to tell her how you feel mate, ask Kate to pass on your email address, and see what happens, but if I were you mate, I would put it in the past, you can always have a smile to yourself with your memories Shane
