If you don't like big crowds the Miracle will be good for you. Yes, it will be gawdy and outdated compared to the Panorama but the flow around the buffet is good. The Radiance seemed just as crowded or more crowded than the Panorama to me, especially with the narrow chokepoints around Guy's and Blue Iguana being ridiculously narrow. For a nice uncrowded walk try deck three exterior on the Miracle. You can walk around almost the entire ship outside including the very aft behind the MDR. In the front you can go inside and continue around Gatsby's Garden and complete a loop. Deck 10 is similar for walking around almost the entire ship. I will be on the Miracle for the 8th time on Nov 2nd for a quick 5 day cruise.
