you have to be real careful and not prejudge people because of their weight. I have a friend who is normally very thin who in recent years developed a medical condition, which requires daily medication that has added a significant amount of weight on her. It was take the medicine and deal with the side effects or die
After a great deal of coaxing, I was able to convince her to go on a cruise (she loves cruising), but she was concern about how other people would react (she actually weighted as much as I did). What she found out was that 95% of the passengers did not care !!!!!
