Models.

I have four cruise ship models.

The Costa Serena, Norwegian Breakaway, Splendour of the Seas, Explorer of the Seas.

The one of the Costa Serena is silver and not part of my question so i'll leave that model for what it is.

My Royal Caribbean models are exactly the same when it comes to scale and the Norwegian Breakaway model itself is the same scale aswell i believe but the plate it is standing on is higher then the ships of Royal Caribbean wich makes it looks like the scale is smaller but it isn't.

So my question is: are the plates the ships are standing on the same height with the Carnival models as the ones of Royal Caribbean?

Thanks in advance.
