Goodness, there are so many beautiful resorts in Cabo, both AI and non AI. I was married at the Sheraton, which isn't AI, but I had a smaller wedding and it worked out better for us. Have you thought about contacting Tammy from this forum? She is a travel agent and specializes in Cabo, maybe she can help you come up with a few options that will be suitable from you and your guests.
Best of luck, I' am sure you'll find all the help you need on this forum.
