Royal has found the Radiance class pretty useful. Seems like the new smaller ship is coming and 90,000-105,000 ton range it will need to fit under theTampa and rebuilt Baltimore Bridge that will likely be higher than the old bridge. At ship can be heavier without being taller I would think. I would also suggest that you could create a sister version for Celebrity using the same hull to replace the M class.
With 8 smaller ships aging out and more and more ports putting in daily passenger limits and new ship in the 2500 passenger range is needed quickly. You could built 2 of these for the price of 1 icon.
