Alright Weddit. I really need some insight.

This could also be tagged as family maybe?Anyway, military husband and I met in my hometown of Savannah, Ga. We have done the paperwork and have been legally married since January. We decided to hold off on the ceremony to bring our families together because (as we all know) weddings are fr*icking expensive.We're moving several states away before the end of the year, and we are going to be coming back to Savannah at the end of 2018 to have the event, because both my parents and siblings (and his) will be traveling for it no matter what. This city just makes more sense. I also have a lot of local friends who are gifting me their services (photography, bartending, etc) to cut down on costs, but I'm stuck about lodging. MIL & SIL (with her 3 year old) will be flying in from CA. FIL and his wife are coming from VA. My parents, grandma, and little brother are coming from a few hours car ride away.Hotel blocking is some serious cash we don't have (and neither does any of our families), so my first thought was find a huge Air B&B right? Great! Found it! Hosts 14 comfortably, has separate rooms, for the duration we'll be in town it's a total of $55 per night per person when it's broken down. hallelujah chorus hereSo I tell FH (H?) and he's like "yeeeeaaahhhh that's not gonna work." Me: "Okay. How come?" H: "Ma (MIL) refuses to stay in the same place as Dad (FIL)." Me: "But they'll be sure to have complete separate rooms." H: "Doesn't matter. Ma won't do it. I know she won't."We both don't wanna hotel block. But we don't want to have to be renting out several Air B&Bs either. I'm stumped for options. My parents could find a place to stay with old friends if need be, but there's no spare place for his family since they aren't from the area. I have no idea how to solve this because I love them both so dearly and I just wanna put my little bridal foot down and demand they play nice that weekend but I also don't know the reasoning behind Ma not wanting to be even in the same house. I also don't want to make her uncomfortable.For background on Ma, she's from Taiwan. I'm thinking there's some cultural thing I'm not understanding, but I'd really like to know without seeming like I'm prodding. I'd like to have the conversation in person with her, woman to woman, but I can't as she's in CA.Any insight on what her qualms might be and how to alleviate them, or ways to find a better solution to lodging would be so appreciated.TIA, you magnificent people. via /r/weddingplanning http://ift.tt/2tFP8h1
