Long Distance Wedding

So my fiance and I are in a long-distance relationship (I live in Oregon and he lives in Georgia; I met him when my family used to live there). Both of our families are on opposite sides of the country. We decided to do our wedding in Georgia because it's more cost effective for us and he has more connections, but that means my family has to fly all the way over to Georgia and stay for quite a few days. My family isn't rich by any means, and we don't have a lot of options as far as lodging with other people. My mom also has my toddler baby sister in which it will be really hard to take an all day flight (obviously she will if she has to, but it just sucks). Not to mention flights and lodging is all very expensive.

Do you guys have any suggestions on how I can accommodate my family while still being cost-effective? I hope my question makes sense.

Thanks in advance!
