Did this last year and she loved it. Got a room out of town in a nice city near a nice mall. Got her a $800 worth of VISA card, and dinner reservations at a Steakhouse The hotel , shops and dinner were all right there together.
Went 2 days after Christmas , I printed out pic of hotel and shopping and restaurant and gift wrap with the cards and a card telling the plan for her day Sounds cheesy but she loved it.
