It can be an option. It really depends on if there are tables available on your day. Yesterday there was a VIP tour group eating lunch in the club. They were told at the last minute, and one person wasn't dressed appropriately and had to go back to their hotel to change. He showed up about 45 minutes after the rest of the group. It is a case of if there is room at the club, they will accommodate you. If you are booking simply for this, it is NOT a guarantee. The best option if you are serious is to book at the 30 day mark, put in your request so you are at the top of the list, and perhaps pick an off day like Mon-Thurs. More space in the club then.
