yeah I know what you mean, there's a name for it I think, something like Movies under the stars.

I THINK I've seen it on the beach by the beach club/yacht club but the advert I saw for it was at the wilderness lodge it looked (which I've NEVER seen it at in real life) but then it's been a while since I've been there so perhaps it's a new thing.

Hmmm hope someone knows for sure because it sounds like a relaxing way to spend the evening
