If there was a nice place for a wedding park and reception area overlooking the ocean and beach- I would use it. I attempted the Romantic park but it just didn't go well - Sims kept wandering off to the fountain there was not much room either - I just have not made my own - as I sort of wanted a beachy looking wedding and really haven't found the kind of area I have in my mind. It was a lot easier when we had nice big beach areas and more wedding designed kind of items and clothes - so I just consigned my self to have a backyard wedding for the few I have held.
