I've seen them and sailed among them. That was an experience, I must say! If your world had them, then you must have heard how dangerous they can be. Icebergs and ice floes. Magnificent, but very deadly to a ship astray or to people who are trying to cross the ice on foot.

I've been worried about Sansa and I guess I'd better worry about Jon and Daenerys as well! Delight's Housing ended up on South Island, as far as I can tell from the responses to Henry's network call to the Guard. So, your house and mine should both be there. After we visit Maglor on East Island, we'd better sail around to the south and check up on our housemates.
