Thanks CBB !! Yes, I called Carnival to discuss scooters with them. He said since I have a "normal" sized cabin, make sure I got the 21" wide scooter.
I noticed while watching the videos on Youtube the elevators are small on the Jubilee (doesn't make much sense since this is a huge CON of the boat.) Everyone is in a hurry to get where they are going they can get down right rude. We will try and work around the major elevator usage times, Mealtime and people getting off the ship.
