Island Living; is it lacking?

I really enjoy this pack. The BB is awesome and I love the world. I spend most of my time there when playing. I like the little events like community bonfire and turtle hatching. The Kava Party is also fun. It could use a few more activities, ability to have more than one Sim on a boat or Aqua-Zip, and multitasking in lounge chairs. ?

I’ve never played with mermaids, so obviously I don’t have an opinion on whether that’s an empty part of the game.
