Visitors post delivery?need advice!

Mamas who have already had your twins how many visitors did you allow once you were home? My mo/di girls are due January 17th but MFM says they’ll be here before Christmas which puts us at 35/36 weeks. My in laws and husband’s sisters are all insisting on coming to our home (each sister has three kids) to “help” and being here for Christmas. I’m not about it. Especially with it being flu season and having preemies. Am I being unreasonable? MIL and FIL also would be bringing their dogs and my other sister in law who has Down syndrome and requires a lot of care and supervision. They all want to stay at our house (to save money they say). We have a modest house 2300sqft 4 bedrooms 3 baths but I already have 3 kids soooo obviously I don’t have room for 13 extra people here. Any advice ladies? Hubby is making me feel like I’m being silly but I’m already a germ freak as it is.
