Does this sound like a fun 13th birthday for my daughter?

That's a great idea! But How bout when you guys first go into the limo you could serve like maybe pop,lemonade,sandwiches etc. When you go to the mall let the girls go by themselves. Unless you want to go with them you can. Let the girls just have fun in the mall. When you go to the spa you should tell the person that will do you nails and stuff to do it very nice.Once they change into PJ'S while they do that you should keep them in her room tell your done making a photo shoot. The movie theater would be awesome. When you wake them up you should have the breakfeast done already. Then when you play hide & seek you should let the prize be Idk a necklace or somthing kinda pricey. Hope i helped :)
