Posting the photo's for now. WIll get back to this soon to give a full review!
You will find this room tucked away right down the bottom of the building near the Post boxes. Once you've found it, the room is reasonably well appointed with decent facilities. A few repairs were needed when we visited. I hope by now they have been!
Overall: Pretty funky. Baby change only in the disabled toilets. Clean, quiet and secure.
Good Points: No automatic hand dryers. Easy to find (follow the arrows next to the information desk).
Bad Points: No stand-alone parent room (change table in the disabled toilets).
This is good info to have on hand, especially if you're gonna check out Babies Proms during the year.
