My bachelorette party is going to be in Nashville. 3 of the 5 bridesmaids live in the area. One is planning on driving to Chicago from Wisconsin so she can road trip with us. However my future SIL lives in St. Louis and expects us to pick her up on our way to Nashville. This will add an hour and a half to our drive each way. I found a train that will take her from her house (train station is 30 min away) to Chicago for $49 it would be a 2 and a half hour train ride. She is mad that i don't want to detour everyone else to pick her up in st. louis. She thinks the train is a terrible idea. She is now threatening not to go. I want her there because we are family. any advice? (another tid-bit about her, I am pretty sure she is mad at me about the party anyway. We are going March 25-27, her birthday is march 30. She made a comment that we would celebrate my bachelorette party on saturday and sunday and that the friday we would celebrate her birthday. I told her no. So I'm pretty sure she's mad about that.)
