Creative Birthday Surprise for 17 yr. Old?

Question

My friend is turning 17 in a few days and a guy friend and I want to do some CREATIVE and sneaky surprise for her. Something that involves getting her out of the house so we can do something. Preferably if this were inexpensive. We were thinking of making her a cake but would like some very creative ideas for her 17th birthday. Are there any out there?

Answer 1

make like a scavenger hunt. make her drive around the city place to place for another clue. then at the end of it make her have to find a key to someones house where u have the party but put it in a cake. if u make it then it doesnt work out so well. but if u dont make it go to a bakery or a grocery store and have them put the key inside the cake that way she has to dig thru the cake to get the key then she will go to the house open the door with the key and then everyone can yell surprise. sounds like funnnn
