I hope you both enjoy your trip. I've never been to Boston, but a close friend and their significant other may soon be relocating there, so I now have an invitation.
In terms of facilities at T5, one thing which did surprise me was the absence of a post office - or even a post box (I suspect there is the latter but I've not noticed one). In T3 there is a small post office opposite the entrance to fast track security.
