Please define the term, "new generation of park goer".
It has not attracted interest to that area of the park. WS is not a "must visit". The very specific area where "The Frozen Ride" is located is a "must visit", nothing more.
World Showcase has never had any problems providing entertainment for young and old alike. The problem more lies within the mindset of how a person views the experience. Many people equate their experience in terms of how many attractions they squeeze into one day for the amount of money they paid. Yet look at a majority of Disney commercials and how they sell the "making memories" aspect of a trip. Some friends of ours just returned form a spring break trip to WDW. They have 2 young children who both attend private school. They did not even ride FEA. However, they did tell me about the wonderful experience they had learning with their children as they visited the pavilions in WS. Even the childrens eyes got big as they told me about the "big building in Japan", the chocolate in Germany and the street performers.
Whenever someone says, "World Showcase is boring for my kids", I want to ask them if they even made an effort as parents to participate in the myriad of fun activities you can experience with your children througout each and every pavilion? You know, the old "making memories" aspect of the trip. Or is it all about posting that picture on Face Book of entering the FEA queue so your friends can see , "how great of a parent you are" and "how much fun your having"? The parents who want to enjoy time with their children are the ones actually at the Kid Cot stations with their kids while they color and get stamps,... not standing 20 feet away scrolling through their phone as their child looks up to show them what they have created , but mom or dad arent there to share the moment.
