Okay so my first impressions based on a few hours of play, I like it all so far.
I bought 'You're on a boat' for my two sims, it's a nice little houseboat but the bobbing isn't so good, I have always suffered with bad motion sickness and get terribly sea sick so just watching the house bobbing up and down was making me feel woozy, night time on fast speed I had to zoom out to map view till they woke up.
So not sure if I shall stick to dry land for a home in future, maybe I'll adapt to it.
I checked them into sparkling sands for a couple of nights to try that out, I had no idea about the weddings that was a big surprise, two women got married while I was there, one was called Minnie Mousse
When my sims got hungry I did the dine with interaction, it didn't really work as I expected, they did sit together but they wolfed the food down in seconds then got up to get more, I thought they would interact a little more, the other guests seemed to.
The diving is fun although on my first trip to Rocky Reef one of my sims came straight back up again for no reason I could see and then of course couldn't dive again for ages, that was a bit annoying but I just sent him home and had her carry on alone. Already had a shark attack but she beat him soundly and got one of his teeth, was worth other 1000 and extraordinarily unusual, much better than being eaten by it.
I've also been playing with the free resort, up to 4 stars so far, I admit I cheated for cash to fix it up, but this is more of an exploration of how stuff works than a proper game. So far it's been relatively easy, my staff have been pretty good it's my sims who are the problem, they will keep talking to them which stops them working. And while she was off diving one day he decided to skinny dip and all the staff got in with him, I zoomed the camera back to the resort to find them all lounging naked In the hot tub
There was something that I was very pleased to see though and that was more stuff in CAS for the other age groups and not just all young adult/adult things, the toddler clothes are adorable and it's always good to have more elder clothes for dynasties.
I'm a little disappointed in the choppiness of the boats, it seems to lag then jump forward every few seconds which is something I noticed on one of the live broadcasts, I remember thinking at the time if it does that for them and they surely have a better computer than me what will it be like on mine? I just find it a bit strange, you can drive a car all about town without that happening why does it happen on the water.
But other than laggy boats and my misbehaving sims I like it.
