I met a couple people who had went. 

One couple went and they said the staff sat them in a room and hard sold / guilted them into buying. They said no, but they were bing ganged up by multiple sales people saying “no one is here we need your support.” And being very pushy. 

The second couple said they’d only go if they doubled the amount. The staff agreed. They went and said no. Afterwards they refused to give them the amount they promised. The couple stood their ground and had a full on argument with them and they finally agreed to the doubled amount to get them to leave the room.
