Yeah, I planned a 4 day trip for a group of friends last August, and we went to Evan Williams. One thing you'll find as you start going to these places is that the tours are all generally the same. You learn how they make bourbon every time, drink a few tastings, then check out the gift shop and get going. Not saying they tours aren't worth it, but it's always great when you can find something different and unique, which Evan Williams' provides if you do their "Speakeasy" tour. They only give it twice a day, and you need to reserve tickets ahead of time, but it's worth it for something odd. The bartender is a character actor from the 1920's prohibition era, who talks to you about the "current events." He teaches you about the "Bottle In Bond" designation, talks about how bootlegger operations work, and pours 4 whiskey's along the way, including EW 18 year, something you don't get on the regular tour. You also get Pikesville rye, which is worth a try. It's worth the effort to make it if you can.
Bulleit was a standard tour without much flare. Their bourbons generally aren't anything special, so not a big deal if you don't make it over there. Can't speak for Angel's Envy.
If you want to copy my homework, here's my google spreadsheet of Bourbon Trail research for my trip. I like to plan out these things like I'm going to Napa on a winery tour, where I schedule and reserve all the good places weeks in advance. Our trip included a day of eclipse viewing in Franklin, so our schedule is a bit different than what you would be doing, but our Saturday schedule is something you could copy. Buffalo Trace/Woodford/Lexington/Four Roses in a single day is absolutely great. Copper and Kings is kind of unique since they do brandy as well as other liquor. It's easy to hit in the evening before dinner if you have time and are staying in Louisville. You can walk from there back towards downtown and hit some good food, bars and breweries on the way. You MUST go to Royal's Hot Chicken and get their hot chicken, it's the best spicy fried chicken I have had in my life, even better than Max's and Uchi's.
If you need non-alcohol stuff to do, the Kentucky Derby was really cool. I highly recommend watching the video in the 360 theater. Mammoth Cave National Park was awesome too, but you need to get there before 4 to get on a cave tour.
