RiseGrace1 you might be interested in Royalty and Legacy. That has learning to Waltz on a special dancefloor and it has sailboats. I'm finding it to be the most playable pack for a while just in terms of the new gameplay. I've been a bit immersed in it. My Sim has been learning to swordfight, hunting pirate treasure and working her way up in society.
The movie theatre was added in Anchorpoint Wharf with Growing Together along with some more much needed activities for kids. I like the treehouse and I have some lucky little Sims that have the playground equipment from Adventure Awaits in their back garden. I was a bit bored with the usual stuff.
But if you're finding that the game needs some livening up a bit there are some Sims challenge suggestions in this section of the forum that might appeal to you:
