Vacation to Kentucky

I am in the process of packing to go see family in Kentucky! I haven't seen some of them in over 2 years. We have some cool day trips planned, including the Ark Encounter. I am very excited about that, I just hope it's not too busy to enjoy. Have any of you been there? What about the Creation Museum? We are trying to decide if we want to try and fit both into one day even though the drive is about 2 hours from one to the other and we already have a 2/3 hour drive to get to the Ark. I can't wait to spend time with my family and enjoy our 4th.
