I'm doing some research for a friend's upcoming first trip to the world. They are coming at the end of March and think they want to stay at the Poly. They have 2 young children (3 and 5), and want to be convenient to MK. They want some suggestions for room locations. They may be interested in concierge. Is there any construction going on right now? I don't know much about the Poly at all, so any help would be great. Also, what kind of rates should they expect with short notice?
