Well, everyone is different. We can't say for sure whether or not she will get annoyed by your being good with money. I grew up with some money, probably not as much as her family has

, but certainly enough. Even so, I am extremely tight with money because I knew that my father had to work very hard to get there. My father paid for me to go to a small, expensive, private college, just wrote a check and paid in full, but after that, I didn't want to take handouts from him. For almost a year I even lived in a trailer with no heat and hot water because I did not want to take his money anymore.
It sounds like she might not have ever watched her parents work

, but even so, you never know. You can't predict how someone will act by how much money they currently have.
If she was really shallow and all about the money, she probably would not be dating you right now at all, so that's something to keep in mind. When you go to Florida, just be yourself. She knows you're not rich, right? So if you seem excited and impressed with it all, I don't think she will be shocked.
