Prototype. Deck 3 is measured — every room is read off the vector geometry in Disney Destiny's published deck-plan PDF, which is drawn to one true scale. Tap a space to see whether its outline was measured, split out of a shared outline, or reasoned. The bow and stern carry no guest spaces on the plan. Decks 3 and 4 are vertically registered from Disney's published plans, including the Grand Hall overlook. Deck 8 is modelled: its stateroom arrangement follows the published categories and numbering scheme but individual cabins are illustrative — check the booking system before choosing one. The remaining decks are hull massing only. Walking distances are computed from the geometry and are estimates. All artwork is ours.
