Honestly no. I was exited about this pack....but it doesn't have enough content, not enough for me to say that it's worth 40.
The world is beyond gorgeous yes, the CAS and Build/Buy are great yes, the swimming/water animations are amazing, but the gameplay itself? It lacks depth yet again and it lacks in quantity.
Depth because for example. every sand sculpture sims build is a great one. They are all idiot savants and unlike in previous games there's no chance at failing to do one or making one of bad quality. Another example is the fact that there's no reward for completing that stupid rabbit whole mural that takes ages to complete. Another, is how snorkelling won't allow sims to find things or how you can only snorkel in certain areas of the world whereas in TS3 you could do it in any body of water you could swim in. The new cultural stuff just isn't there, or it's all recycled from previous packs.
Quantity because there's not enough here, there's some beach activities and that's it. No new skill, no new system, no scuba diving lots/neighborhood, only two boat types you can ride, and a lot of rabbit holes.
I have also expressed my hatred for all things world exclusive before with CL and this pack delivers on that, yet again. Much like City Living it has exclusive lot traits yet again, and exclusive festivals yet again.
