10 POINTS! What should my friend do for her birthday, in 3 weeks time??!!?!?!?

Hi, she dosent know what to do. her birthday is soon, but all of us (her friends) are going on holiday when she was going to plan her party, so shes doing it the weekend before. She dosent want to go to the beach, spa treatment, disco or anything like that. she dosent want to go shopping or go to cinema becuase thats just normal to us. Can you think of any ideas, 2 years ago she did a fancy dress thing, but this year i was thinking she could do an 80's fancy dress of something? I dont really know, got any ideas? x
