No, humans shouldn't go on vacation in space. Because then they would have to wear those suits that you need to get air. I don't think that people would want to wear those suits. Because when people go on vacation they want to relax not have to do all that hassle while they are on vacation. also because when people are on vacation they like to lay in the sun and relax and in space you cant do that. Because you can't receive oxygen the way you do on earth. I think that it would be a nice experience to go to space. But some people don't like wearing those oxygen suits. Also i think that i would never go to space for vacation because thats not a place that i would like to go to. Because i would have more going to a place where its sunny.
