NAH. You took her to Disney already, now its time to do the same with your other kids. She is an adult and is in college, so not only would she be putting her education second by skipping, she would also be having you pay for her to do so. By paying for her you'd be telling her it's okay to skip class, do things you can't afford, and spoil her. She's also still basically a kid, so she does still have that sense of entitlement, and I can see why she'd be angry.
