I think it is good to have visitors to see you because it can be exciting and fun. For example, my dad visited me in Korea and it was nice because we could talk and I was able to show him some cool places.
This post makes it look easy for having visitors, but I actually had a lot of difficulties meeting with my dad. I will add some tips to help readers. At first my dad did not understand the subway system well enough to be able to meet me at certain stops, so (TIP 1) I recommend visitors to consider taking a taxi at first. Another tip I have for visitors is to (TIP 2) use cafes for wifi if your phone does not have data.
