Update: We just returned from our Europe trip and we had a wonderful time. As I wasn't able to get into see the NFC I settled for a day at the BritishMuseum and a tour of Westminster Abbey and Buckingham Palace. We then headed to Italy
for the remainder of the trip. I always enjoy Europe and especially enjoyed seeing the kids have this experience for the first time. We'll be back and I will certainly reach out to the NFC staff earlier to see if I can get into see the collection.
Thank you all for the suggestions and comments. I appreciate the forum so much.
