Looking for a colorful, but quiet environment? I recently explored  The Blue Lagoon of Greenburg and was  pleasantly surprised!
It’s a lovely mix of the tropics (the lagoon, the jungle-like plants and cosy huts), fantasy (floating islands like in Avatar’s Pandora) and I even found some pre-historic scenes (dinosaurs!!!).
All over the sim are spots to sit and enjoy, some romantic for couples, but when you are travelling alone or with ‘non-romantic’ friends its great too! 
On the floating islands you can dance by using the popular intan-couple dances, making it a great night out with a special someone if that’s what you are looking for!
