Road trip with 3 month old??

Hello to whoever this reaches! My husband and I will have a 3 month old around the time of holidays this year and are debating seeing our families or not. His family is an 18 hour drive from us, meanwhile my family is about a 7 hour drive. I’m not sure how our baby will be around this time with sleeping but I know it’s recommended to take baby out every 2 hours to stretch/feed/change. I personally feel like going to see his family is way too much, but my MIL is upset we aren’t coming up. Any tips/opinions on traveling with baby are welcome! On a side note is traveling to my parents an option since it’s shorter? Or should we just opt for staying home and trying to invite them to us?
