After 3 sailings on Mardi Gras and 3 sailings on Celebrations, we're having a hard time going back to the smaller ships, with all the new options for food and drinks on the Excel class ships... We always do a basic balcony cabin, but spend minimal time in there - outside of sleeping, so the Havana options wouldn't have an impact. I didn't notice much of a difference in terms of crowds between Mardi Gras/Celebration and Horizon/Vista.
