I honestly enjoy OR. It's best for collection and exploration though. And it added the herbalism skill. Which tends to be useful in the second Vacation pack, Jungle Adventures.
But to be honest, JA is a very beautiful world, but the exploration aspect of it is tedious and boring compared to WA. I absolutely HATE the archaeology skill. It takes way too long to crack open a find. I gave up on it after exploring a couple of temples. Not worth it aside from the stunning beauty of the world and the BB assets.
If I play sims 3 it is for WA alone. And I do have a current save where my sim is working through the tombs since I never completed it.
Sims 4 vacations? No. There's nothing to do unless you are collecting for herbalism or exploring the jungle.
In GF, I added a spa and outdoor pool for the campers.
