On the Dream-class ships, there's extra space near the verandah that can be used for luggage or anything else. It's easier to walk around the bed and other furniture. The coat hooks aren't in a stupid place. The shower is in the round bathtub instead of the normal, rectangular one. Everything just feels a little better.
My first few cruises were in Family Verandah rooms. Last year, I finally took a cruise with a regular Verandah room and I definitely noticed the difference. I'm going back to the Family Verandah rooms for future cruises on the Dream-class ships.
