6 month anniversary delivery problem

Hi there, my girlfriend and I's 6th month anniversary is comming up on the 22nd of August, but i have a small snag. She is a off at her camp for the entire month of August. Now I have an idea of what to do, just need a bit of feedback. Her camp is about 6 hours away. So my plan is to make a vase for her, personalized and such, and fedex it out to her a few days before. All wrapped up of course and a attach a not to the outside saying "don't open until lunchtime on the 22nd". And on the inside of the package, have another note saying something of the sort " There Will Be Something By Shortly To Fill This...". And i would plan on showing up to the camp around lunchtime, with a dozen roses and a gift ( a bottle of her favorite perfume ). I am also thinking of sending it out with her when she leaves, so she has to sit there wondering what the gift is. Anyway, feedback please, and thank you in advance.
