I hope this is okay for this thread as it's not in Isla Paradiso but is houseboat related.
I thought before I load up my dynasty I better check to see what is possible in Riverview so I added a port and built a little houseboat, just as I was moving it I could see that Llama mascot off in the distance, just no escping those things
I copied the port lot from Isla Paradiso, it was port plenty, not too easy to find a spot it would go without it sinking the ground too much, in the end I got it to fit on the tip of the central island with a bit of terrain smoothing.
But while it's sort of neat to have a houseboat on the River you can't go very far with it because the bridges are all fakes, it's land with a facing on, so this was the end of my journey.
So not sure it's worth the hassle of adding ports to town unless you really want a houseboat but you can at least do all the other activites like windsurfing, and snorkeling, I do like the fact that first Seasons and now Island Paradise have made the water something you can have fun with rather than it just being a part of the landscape.
But back to Isla Paradiso where my sim found a squid in Davy Jones Locker, I thought it was such pretty colours I had to get a close up pic.
