Dining with my mother in law for With ddp, she will be booked on a package with brother and sister in law, just wondering when we dine with her (MIL) will she need a pin to pay with DDP after scanning her band or will they just scan her band and thats it. Thanks and I hope that makes sense.
since she is registered in your brother's room, she will need the PIN assigned to that room. and she will need to enter it for every transaction, even purchasing a snack.
