Separate makeup artists

So my bm are paying for their hair and makeup. I have a mua coming to the hotel and can also do my BM for $65. Two of my bridesmaids want to use their own mua. That's fine. First their mua wasnt coming on site then she was, now she isnt smh. It's really screwing with my day of timeline. I wanted to designate a time for makeup in my timeline, but I guess that's not happening now. I know when I want them to be there. We were serving them lunch. I guess they're going to mess up their makeup? It would be much easier if she could do their makeup onsite after lunch. I dont know I guess I'm just venting.
