DH and I are trying to make plans for his spring break...

He has proposed a multi-day road trip with a cumulative 12+ hours of driving, probably spread over 4 days (with the longest stretch between destinations being about 5 hours). I will be 20weeks pregnant by that point and plan to work in lots of breaks to stretch and stay hydrated.

Are we crazy to even entertain this kind of road-trip during pregnancy? If not, what other recommendations would you have (besides frequent pit stops, lots of water, and snacks)?
Thanks in advance!
