S.,
Have you asked your daughter what SHE wants?? This is HER birthday, not yours.
If she doesn't like a lot of attention on her? Then having a big ta-do will only serve to make her uncomfortable.
Find out what she wants. Look at your budget and see what you can afford. What if she just wants a spa day with a few friends??? Are you doing this for HER or are you doing this for you??
It would help to know if this is what she wants, what she likes, etc.
My daughter did NOT want a huge party when she turned 16. She wanted, of all things, to go bowling!! LOL!! with a few friends...that's it. she did NOT want some huge party.
So ASK HER what she wants and what SHE is expecting...get her involved...this isn't a surprise party, is it?
