I'd like to take this one day at a time and make some suggestions:

Leave Goldsboro, NC @ 7:00 a.m. Arrive in Nashville, TN @ ~4:00 p.m. (including 1hr time change) See Country Music Hall of Fame Go out to dinner with sister-in-law Crash in hotel
OK, you've left 9 hours to make a trip of 591 miles. If this were me, I'd assume that I wasn't going to make it in 9 hours, but in perhaps 11. You have to stop for food, gas, and pit stops. Did you pull the travel times from an online mapping website like Mapquest? They're notoriously wrong. If you really, really want to make Nashville before the Hall of Fame closes (and leave enough time to SEE it), leave at 5 in the morning. That means packing the car the night before.


December 5th - Breakfast w/sister-in-law Leave @ 10:00 a.m. Arrive in Oklahoma City, OK @ 9:00-10:00 p.m. Crash in hotel
This is not a good idea. Chances are, you're not going to leave as early as you think. You've got traffic through Memphis to think about. Also, this is almost 700 miles -- as others have said, you should only plan to drive 600 miles MAX in a day.

December 6th - See Oklahoma City memorial See National Cowboy & Western History Museum Leave Oklahoma City @ 1:00 p.m. Arrive in Albuquerque, NM @ 10:00ish p.m. (including 1 hour time change)
Possible to make this drive in about 10 hours, but have you looked into the opening times for the places you want to see?

December 7th - See Indian Pueblo Cultural Center Leave Albuquerque @ 12:00 p.m. Arrive in Las Vegas, NV @ 10:00 p.m. (including 1 hr time change)
Once again, this is almost 600 miles (11 hours drive) after a sightseeing morning.

Like the others, this is a lot for a body to endure, and I don't think it would be pleasurable either. My husband and I don't USUALLY sightsee on any driving day of 500 miles or more. We have done it on occasion, but usually end up talking about it later and then regretting it.
