Is World Adventures worth buying?

Although I don't much care for the tomb exploration or quests, I don't mind visiting the vacation worlds because they have some very pretty elements and a little down-time for my sims isn't such a bad thing. I don't need my sims to be doing exciting things all the time. I have traveled extensively in my life and some of my best holidays were ones where I didn't have tons planned and spent relaxing time getting to know the people and enjoying the food and scenery. I guess I like my sims to live as I do - nothing too exciting, with quality time around family and food :p
I do, however, love what the EP adds to the game even if my sims never set foot in one of the vacation worlds.
