Big rectangular room. Escalators on both ends. Green lane is on the far right by that escalator. Blue lane is in the middle so if you check in at the larger numbers, escalator on the right would be closer. If you check in at the smaller numbers, you are closer to the escalator on the left. You can use either escalator. You could even go to the ship and then switch lines. Entrances are not that far apart. You have no opinion as to which person checks you in. It is just the next available. Handicap is on the far left near an elevator. Maybe suites check in there, too. I did not notice. Only noticed the handicap because of all the wheelchairs, walkers, and scooters.
