Little Mermaid characters can be found in the carpeting at Beach Club. Nemo characters are now in the Caribbean Beach rooms, while princesses (who lived during varying time periods) have come together for some kind of 'reunion' in certain rooms at Port Orleans. Bambi, Chip, Dale, and Meeko (from Pocahontas) can now be found in Wilderness Lodge's bathrooms.
So as far as character overlays go, I think this one is sensible enough. From what I learned about the Victorian Era, English culture influenced culture in the US during that period - GF even has its own location for afternoon tea. So if GF had to get a new water play area (Disney seems to be building them everywhere now), I think this theme works.
