Hi neighbor... I am south from you.
I have to say that I am divorced and have a 10 year old boy and I have even thought about going by myself. There isn't anything to be guilty of. Girl teenage years are tough and her not going has nothing to do with you, perhaps there is someone she likes, is there something at school that she doesn't want to miss, or is it she has a group of friends that she can't bear to be apart from now? Some of this can factor in and it could be just a case of she doesn't know if it is cool or not. She will come around and go with you again, in the interim just go and have a great time. Bring her back presents and call her from there to tell her you wished she was with you.

I hope you go and have fun, I am planning on a Oct 2009 trip with some family members but you better believe that sometime soon I will get my butt on a plane flying out of AC for a solo trip where I can be the kid in Disney. It's good for the heart you know.....
