As per the OP's experience, I think others enjoy putting down solo people because of the perception that solo people "are losers who have no friends". QUOTE]
I don't think people enjoy putting down solo people. I think the majority or travelers feel bad for them because they like having companionship on their trips. I think the man the OP was talking about was definitely rude in yelling to her "how sad" but I don't think he was trying to be mean. Reading this thread has been really interesting because it seems a few people are quick to respond with comebacks or other slightly rude comments. It seems like they are insecure about traveling solo. Honestly though, so many people are wrapped up with themselves, their families, and their own trip that I don't think they really pay attention/notice other WDW guests.
