Is there a polite way to request family members who have invited themselves not join my vacation?

I'm a single female in my 30's. A few years ago I took a trip to Europe alone. This year I mentioned to my mom I'm considering traveling internationally again later this year. She said my two aunts would love it and told them I'm planning this trip that they have now started talking about as if they were invited to join. Although I love my aunts and don't mind spending time with them I prefer to travel alone. Is there a way to basically say please don't come that won't be seen as rude? They're both retired so scheduling conflicts won't work.

Tl;dr Wanted a solo vacation, they invited themselves. What do I do?
