Here is my own renditions and ideas. This by no means for sure will happen or are official. Nor have I heard any rumors or truth about any real ideas. Feel free to add comments on your ideas. I have a poll going on right now and when the results come out, I will either reiterate these ideas or link to this post. These are also the options from the poll.
Rollercoaster
Got the idea from the Hulk rollercoaster. I'm not a big fan of rollercoasters, but I can imagine that the cars can be in different colors as the rangers and be like a rainbow coaster. And maybe have a select villain.
Enclosed 'Dark' Ride
A ride like the ones at Disney (Small World, Peter Pan, Snow White, Winnie the Pooh, etc.) or the Spider-man ride at Universal Islands of Adventure. The ride can be 3-D like Spider-man or be like the ones I mentioned before with animatronics that barely move. They can tell a story. It could be of any select Power Ranger team, I vote for Mighty Morphin. since it is the best known. Most rides go from room to room, the first room could have Rita escaping the dumpster, second have Zordon telling Alpha to get five teenagers and we see the morphed Rangers appear, the third can have the Rangers fighting a monster or Goldar and fourth Megazord battle and fifth could have Zedd and Green Ranger and so on.
Indoor Stageshow
The Stage show Saban had in 1995 could be replicated or made better inside a housing stadium like Disney has for their stage shows, which are virtually all gone but the ones I grew up with where Beauty and the Beast and the Little Mermaid in MGM Studios. I like air conditioning. And having it indoors, it can have special effects or 3-D. And this show can have different Rangers from different teams and being in-suit, they can have different voice actors. They can take the plot of Super Legends where Zedd returned.

Outdoor Stageshow
Disney Hollywood Studios only had the Rangers in a parade and meet and greet, but back when it was MGM Studios, there was Ninja Turtles and they had a outdoor stageshow and then they did a meet and greet. As we said before, Sentai has plenty of stageshows and most of them are outdoors and they do pyrotechnics. Outdoors could also have a slight arena roof.

In a Parade
The only thing Disney had them do was participate in the Car parade in Hollywood Studios. I have covered this many times before as they had one member from a different team and would rotate members, having a member of a new team replace one from four years before, for example Mystic Pink replaced Pink Time Force Ranger.
Meet and Greet
After the parade and at different times in Disney World Hollywood Studios in Orlando, the suited Power Rangers would sign autographs. To start out again, Saban will probably have all 5 Samurai Rangers and then slowly add a new member from a new team replacing another. I do wish they would have like
Samurai Red, MMPR Pink, RPM Black,
Jungle Fury Yellow and
Operation Overdrive Blue.
Martial Art Demo
What I was thinking of was in-suit but an outdoor thingy where they train kids with simple marital art things and have an actual Martial Arts person be the host and explain.
Game-like Ride
In Disney World Magic Kingdom there is this Buzz Lightyear ride where you go in cars and have to zap targets. So maybe each looks like a zord and you have targets from different series, like one room has putties and Lord Zedd is in command at a park or cave and another has Cylcobots and Ransik is the boss inside a cityscape and another has Grinders and Venjix (a giant tube) in his headquarters, etc.
Museum of History
Ah, I want this so much. I imagine a big space with several rooms, it doesn't have to be as big as an actual musuem but it would be awesome to see suits in cases. They wouldn't have to have all the suits of each rangers but at least a few from each team. Or maybe all the helmets. I mean, there are some fans that have one helmet from each team. Not only suits and helmets of the team but like with Sentai that has Megazords, villains, and vehicles.
