It is rare for us to see that behavior when we have been there but yes we have seen it and have been told stories by CMs. One of the reasons the smaller plastic bottles of water are no longer offered is because many were found stashed and unused in the rooms at checkout. Last visit there was a family that would show up every morning and evening and take the tray from the room (trays are no longer in the lounge either because of this) and fill it up with a line of people behind them. To top it off they would show up in bathrobes and pajamas right out of bed. I know the lounge is a comfortable place and sort of like a family room at home but remember there is a certain etiquette to follow including not showing up dripping wet from the pool. Most of the time the CMs are asked not to upset the guests by confronting them so maybe it is time the rest of us speak up. If not the actions of the few will mess things up for the rest of us.
Most of the time the lounge is a very pleasant place to be but offerings have been cut back and will continue to be cut if they are abused.
