Tipping

Hi loves!
My (now husband) and I were finally able to get married yesterday. I tipped photographers and videographers. They were amazing. Gratuity was included in caterer. I do have a question in regards to my wedding planner. I paid for full planning. It was $1800. We were not happy with her at all. I pretty much planned everything. She was helpful day of and brought 4 helpers with her. They were good. Helped with bar tending (which was literally just pouring wine), helped clear tables. Things like that. I’m conflicted on if I should tip them. She told me she pays them (not sure of amount). I feel that the 1800 I paid her was basically a waste, as I should have just paid for day of coordinating. So is her paying them enough? I’m worried if I tip her, they will not even see any “extra”. I also don’t really want to tip any extra because most of the money we paid her, SHOULD go to them.
