The deluxe insides have a larger sofa thereby adding the extra cabin space. There is also more room between the bed and bathroom. Location is not any better in the ship than a regular cabin price varies by sailing many times the same for both all depends on availability. I'm booked on the Beyond in a regular inside as deluxe was much more but if prices drop I'll probably upgrade. Rarely in my cabin anyway sometimes watch a movie before bedtime. Closet, drawer and vanity space are identical.
