Who's Bringing Kids?

Our tickets can include free admission for kids 7 and under. Mine will be 7 & 4 and I'm debating bringing them. The downside is I'll be traveling to FL and staying with a friend with similar aged kids but 5 & 8. She doesn't want to bring hers so she can have an adult weekend. I'm not at SAHM and it feels like these opportunities will be getting more few and far between over the next decade. What are the pros and cons of taking kids? Especially from out of state? I'm mostly concerned if they're not feeling it that I'll have to leave early.
