If the rooms look as good as I hope they are going to, Contemporary might be on our list to try one day.
My personal opinion from pictures- Grand Floridian rooms need a complete overhaul. I think they look dull, joyless and certainly not worth the price tag. Same with Boardwalk - so dated, they look like a grandma's living room. Not that anything is wrong with a grandma's living room, but I don't want to pay over $500 a night to stay in it.
I think the Yacht Club new rooms look fantastic!
Remember, my opinion only!
