To start off this will be a wedding with maybe around 50 people attending. All over this site I see welcome bags for the guests that traveled from other places to come. Also, some say that they reserved rooms for all their guests at one hotel. Why and how would I do that? I'm really confused whether I am expected to pay for their hotel or risk being rude. I don't mind doing the welcome bag thing but how does this process work? Can anyone explain?
