Differences Seaside vs Seascape?

[LMaxwell]

I was on the Seaside a few years ago and will be on Seascape in 2 weeks. I had no part of the Seascape planning so I really am just starting my research now. I know the ships are the same class, but are there any significant changes/upgrades/features on Seascape that are not on Seaside? Fantastica Balcony level for both.

Lots of good information in this great review. I believe it is the Seashore where the most changes from Seaside and Seascape were made.
