AITA for using my lawn as the background for my son-in-law's wedding?

This all started last July at my (f60s) daughter's wedding. My daughter had wanted to have her reception at our house. I wasn't too thrilled with all the commotion a reception would bring (it was 2 weeks before my daughter and son-in-law went on their honeymoon), but it wasn't an issue for me to let her do it.<br><br>Fast forward, my daughter had a few kids. She is at the stage where her kids are getting married. My 2nd grandchild from my daughter, my grandson, got married this spring. He had this idea where he wanted to get married at his "ancestral home" (his words). He told me that his wedding reception would be at my house. Same exact story as last year. I was skeptical, but my grandson assured me that he would handle the planning and the cleanup. I didn't even have to show up if I didn't want to. I told him he could do it, and promptly forgot about it until the day before the wedding. The day before the wedding, my grandson and his friends came over to my house to set up a tent and a thousand other things. I complained a bit to my wife, who assured me that it would be fine. The next day, I made an appearance, gave a speech, and promptly left to go to a bar. I met my wife there, and we watched the reception from afar.<br><br>A week later, my daughter called me to let me know that her youngest son (my youngest grandson) wanted to get married at my house. He told me that he had gotten the idea from his brother and that he wanted to get married at the "ancestral home" as well. I told him he could do it, but under certain conditions. I wanted him to pay me $5000, and I would pay for all the expenses of the reception out of that $5000. He agreed. His wedding was a few weeks ago, and my grandson handled all the details. The reception was nice, and I didn't have to clean up after him.<br><br>Now here is where the problem is. My other daughter's oldest son is getting married next summer. He also wants to get married at the "ancestral home." I told him he could do it for $5000, and he was shocked. He yelled at me, telling me that I was money grabbing and that he was my family. I told him he could go somewhere else, and he slammed the phone down.<br><br>Now my wife and daughter are pissed at me for wanting to charge my grandson so much. My daughter says that she is going to cut contact with me and that I am a horrible person for being a money grabber. Her husband and her other 2 sons are on my side. They say that I shouldn't let my grandson extort me for free usage of my house. My wife is saying that I'm the AH for being selfish. AITA for charging my grandson $5000 to use my house?
