what do you think of a 8-10hr car ride...

with an almost 4month old baby? i got invited to go on a mini vacation to oregon to visit some aunts and uncles with mom, sis, bil, and chloekins. the problem being that we would all be in a little honda civic and dh wont be going. now i know its just 4days but it would kinda suck because we would be gone on her 4month "birthday". i would like to go to see family on one hand, and we have been talking about goting to visit there but i wanted to go and see family and visit WITH hubby, not go with everyone else and leave him home. i know it makes hubby sad for me to go without him, but he wont tell me. im so torn right now i just want to cry, this is one of those times that i wish we were rich so we could jusst rent a van and all go! sigh, such is life.
