Friends and family

Groups of people or a person could see another group or person and start a conversation as they know each other. This would cause problems as it would block the path and other guests would have to move around them.

You could get security or staff to approach the group and ask them to move on to stop them blocking the path.

These could also increase the group size as well, so the group starts with 2 guests and meets up with 3 guests and then they are a group of 5 guests ect.. You could put it in that if the group is over a certain size and they do meet family/friends this group would not grow any larger but you could have group 2 follow group 1.
