My advice FWIW:
- Hire. A. Personal. Guide. For $70 bucks for two hours a guy will take you around and tell you anything and everything you want to know. Do this at the beginning of your time there to give context to everything you’re seeing. Don’t do the bus tour, for the same price book a guide ahead of time. Google “Licensed Battlefield Guides” and follow the steps. It will seem super antiqued the way they do their bookings but trust me.
- It’s massive. You need time to take it all in.
- The main museum in town is better than the one at the main visitor center if you have background in Gettysburg but both are good.
- Blue and Grey restaurant in town. You’re welcome.
- Learn as much as you can before you go, it will greatly enhance your experience.
- Don’t forget the cemetery where Lincoln gave his address.
- if you have time, I strongly recommend the Antietam Battlefield as well. It’s about an hour south.
