I don't have any advice or suggestions for you, but I just wanted to offer you some warmth and support as I know some of the challenges a large family brings. I am one of six children myself, and my youngest brother was a foster child who my parents eventually adopted. I distinctly recall the occasional side-eye and the infrequent but no less painful comments from waitstaff, hotel clerks, and others when we informed them we needed seating for a party of eight. That's to say nothing of what my parents quietly went through to make sure we wanted for nothing and were even treated to vacations and other activities. If they are anything like me, your children will have countless amazing memories of the time you spend together whether you can find a way to stay on Disney property or not. My family could never swing an on property stay, and I only recall going to the Magic Kingdom once as a child, but darn if I don't have a picture perfect memory of the day I got lost in the crowd, separated from my family as everyone in the whole park seemed to be wearing identical yellow ponchos in the rain at dusk. I was certain I was doomed, only to be rescued by Peter Pan, who almost magically led me back to my frantic mother. I think that memory and nothing else from that trip has stayed in my mind for thirty years because it tells me so much about who I am, where I belong: with my family, no matter what. I know it's a struggle: much of the world doesn't seem built for big families. But big families learn to build the things that matter - the joy, the memories - for themselves. Best wishes.
