She sounds like a sweetheart

! Amber had a good idea about jewlery. You could get her a nice piece for $200.00 and she would have it a lifetime. You could even get in Disney

. They have some beautiful jewlery stores in WDW (it wouldn't have to be Disney themed if you didn't want it to). Does she like to get her nails done, you could pay for her to get a manicure and pedicure before she leaves on vacation

(you could both go there and have a girls day out or you could get it in the form of a gift certificate). If this is your daughter I think a mother/daughter day out together is always special

. You could do a dinner and a movie, or a show, or just shopping at the mall for some outfits to go on vacation with. If you are going to be at Disney during her birthday you could go to a really nice restaurant and celebrate

, or how about an illuminations boat ride

and see the fireworks from the boat:

. I've had several 16 year olds and believe me they usually leave hints

. No matter what you decide I'm sure she will appreciate it
