are a number of apps now available. Disney has their own "My Disney Experience". It has maps, menus, wait times, fatpass return times etc. It is free and available for most smart phones. Touring Plans has an app that shows similar things including their projections for wait times for attractions. The full version comes with membership to their site. You can get a view of the information available on their site. (I downloaded a free version on an android tablet for our trip to
Disneyland last summer and it showed me all rides for some reason)
Undercover Tourist has their own app that has similar information. Some of the apps use historical information supplemented with users input. Disney's uses the official wait times.
I am trying to remember what has been added in the last four years. The big item recently is an expansion of Fantasyland. Belle has her own castle now. There is a reenactment of the story of Beauty and the Beast that has gotten solid reviews by adults. There is also a new Be Our Guest restaurant. It is counter service at lunch and table service for dinner. ADRs are hard to get. Again reviews have been positive.
There is a new Little Mermaid ride. It is supposed to be just like the one in Disneyland. It is a nice ride that tells Ariel's story. There was some use of technology that I found to be neat. I have read the queue has things to pass your time.
Main Street Electrical Parade is now happening at the MK instead of Spectro Magic.
Test Track has been reimagined the track is the same but the interior has been changed.
Captain EO has returned to Epcot taking the place of Honey I shrunk the Audience.
There are a couple of new restaurants in Epcot. Via Napoli is a pizza and pasts restaurant. La Hacienda de San Angel opened in place of the counter service in the Mexican pavilion. Like Be Our Guest, it is counter at lunch and table at dinner. Monsieur Paul's has replaced Bistro de Paris
One that might interest you is the new Star Tours. They have revamped the queue. My daughter wanted to let people pass us because she was watching the droid scan passengers items. The storyline is also new. There are four parts and multiple versions of each - two opening scenes, three first stops, three transmissions and three last stops. Their are a total of 54 ride possibilities and it might take you 10-15 rides to see each scene. The good news is the lines on our last trip were generally short. I rode it six times in less than an hour with my son and daughter.
I am sure I missed some things. The Fantasyland expansion is the biggest item recently and there is still some more to come.
