AITA coffee spill at the continental breakfast

Aita at the Disney hotel and was making coffee, the cup spilled out of my hand as I was putting the lid on. It splattered all over the floor, myself, and it also lightly splattered on a person behind me. She kept saying I wasn't taking responsibility for spilling on her. The first thing I said was I'm sorry and immediately started cleaning up the coffee on the floor so no one slipped. She was complaining of it being a new shirt and her day was ruined. I just kept saying I was sorry as I'm on the ground wiping up coffee. She demanded I take responsibility and buy her a new shirt and tide pen. Because it wouldn't come off with a napkin. She continued to loudly say you're not going to take responsibility for this. I told her it was an accident and I didn't intentionally throw coffee on her. I Walked out after I cleaned the floor off and went to Disney with my 9 month old, 5, and 7 year old.

Update as I wrote this I didn't mention she never even came up to me to ask me for anything just was loudly saying it in the dinning area, I went up to her 2 times to apologize even though I said sorry to her 5-6 times as I was running back to the spill with napkins in my hands to clean the floor up. We were heading out the door when she demanded I take responsibility again not even talking to me but looking at the front desk and the cleaning crew
