Was Crocodile stronger at Marineford? Or was he holding back in Alabasta?

 During the Alabasta arc, Crocodile displayed a level of power that was initially considered overwhelming by the Straw Hat Pirates. He possessed the Logia-type Devil Fruit called the Suna Suna no Mi (Sand-Sand Fruit), which granted him the ability to control and transform into sand. He had a reputation as a Shichibukai and controlled the desert kingdom of Alabasta from the shadows. His strength was showcased through his battles with Luffy and others. At Marineford, Crocodile was present as part of the war that took place at Marine Headquarters. While he did participate in the battle, he didn't display the same level of dominance as some other powerful characters present. This has led fans to speculate that he might not have been as strong as initially portrayed in Alabasta. It's important to note that power scaling and character abilities can be subject to interpretation and development by the author. Oda often keeps details deliberately open-ended to keep the story intriguing.

How long does it take to get from one end of a Royal Caribbean cruise ship to the other?

 The length of time it takes to get from one end of a Royal Caribbean cruise ship to the other can vary depending on a number of factors, including the size and layout of the ship, the number of passengers on board, and the speed at which you are walking.

On average, it can take about 10-15 minutes to walk from one end of a Royal Caribbean cruise ship to the other. However, this time can vary significantly depending on the specific ship and the route you are taking. Some ships are much larger than others, and it can take longer to walk from one end of the ship to the other. Additionally, if you are walking through crowded areas or taking a longer route, it could take longer to get from one end of the ship to the other.

In addition to walking, there are also other ways to get around a Royal Caribbean cruise ship, including using elevators, stairs, and escalators. These can help you get to your destination more quickly, but they may not always be available or convenient, depending on your location on the ship.
