How do I tell her to come later?

My aunts coming to visit. She called me earlier and said she was leaving her house around 10 tomorrow driving 2 hours to the outlets then headed to us after that which is an hour(3 hours total). The outlets are pretty bland there so even though she says she’s shooting to arrive for 4ish I think she’ll be earlier. There’s zero stores she’d like there.

Both me and my fiancé WFH tomorrow. I’m off at 4:30 and he works sometimes until 7. How do I tell her she needs to come around 5?

I was thinking of texting her early tomorrow and saying I have a late meeting so she’ll need to arrive late. Or I could just say with the impending FL hurricane my company asked me to work until 5(I’m not in FL but 75% of my company is).

For some reason I feel weird asking her to arrive late.
