Fishing can be done in all of them, For guitar or writing take a guitar or laptop in inventory. There's a stereo in the china base camp for athletics (although the athletics equipment in the academy is better) likewise there's a stereo in the market in Egypt I think, and I think there's a stereo in the base camp in France but I wouldn't swear to it, there's a chess table in the park in France and another in the base camp, you can cook in any of the base camps although in Egypt you're restricted to food 'cooked' without a stove (ie autumn salad, peanut-butter and jelly sandwiches, and I think sushi might be uncooked as well), photography can be done in any of them (they all sell at least the cheapo camera), if you've already got the first level in Charisma that can be raised pretty easily (and it's a golden opportunity to get the celebrity challenge done for easy friend making in the future), not sure where to find mirrors to get the first level if you haven't already done that, for handiness go round the base camps upgrading the sinks and so on, in France particularly there's a lot of them, obviously less applicable if previous generations have already done that, that leaves gardening and painting, of the original skills. I'm not sure if it's possible to gain gardening by harvesting from all the various garden's in holiday locations, but you could take gardening books with you to read. Painting is more problematic, I do wish that EA would make a portable easel, ie one that could go in a Sims inventory, to be realistic it could maybe only allow small paintings to be done on it?
