My FMIL is generously throwing me a bridal shower. I offered to let her have the shower at me and FI's house; we could easily accommodate 20 guests, which is how many she wants to invite.
For some reason though, FMIL is hung up on having the shower at a local park pavilion. The fee to rent an outdoor pavilion there is about $100. It seems silly to me that she'd pay a fee to have it in a park rather than use our house for free--especially because money is tight for her. Also, the shower is in July. I live in Wash D.C.--it will very likely be hot and humid. I don't want the guests who come to be uncomfortable.
I said to her the other day, "Oh, please don't pay to rent a space! How about we just have the shower at my house?" I really meant it too--I love having guests over to my house! But she responded with, "It would be too stressful for you to have it there. I don't want you to worry about helping with set-up and clean-up." I told her even though I wouldn't mind helping with those things, I'd stay out of them if she wants me to. But she still insisted on the park location!
Is there anything else I can say to her to convince her to have it at my house without offending her? Or should I just let this go?
