I would have NEVER thought to bring a photo ID for DS (10 years old). I figured that once we got our cards onboard, then that was all we would need. We don't have passports and will be using our BCs & DLs. Thankfully, I have a photo a DH from a recent PD fingerprint clinic so I'll use that. I also sent my cousin a message to bring a pic ID of her DS. Thanks so much for this suggestion.
