Yes, I started learning martial arts on it.
My Sim didn't have time to get to skill level 5 with it before returning home, however - he had been busy doing adventures and found this while trying to figure out why the museum guards kept abandoning their posts.
Lol someone should fire the guards for leaving their post all the time.
Unless they were going for you?
You know with the Klepto trait can you steal stuff in the tombs and such on vacations?
Also I just thought of that during your vacation in France you can get items for free for training martial arts, the stuff for nector making, everything that you need to live at your house in one vacation. Lets see 3 items per night so that would be 2 items for martial arts training, 1 nector making machine fir the first night. Second night would be a couple of racks and a fridge. finally the last night would be a bed, bath/shower and a stove. You got most of your basics living stuff plus stuff for your martial arts and nector making. If you don't want martial arts stuff you can always get a couple counters or something else you want.
