This solution will walk you through getting this and four other achievements in one go.

Step 1: Fire up a four player game
Step 2: Beat up on the other players 5 times to earn the "Playing to Win" achievement

Step 3: Make sure one of those player deaths is by throwing them to get "To Infinity and Beyond"

Step 4: After this point you should see a red box floating around that will curse you, touch another player to transfer that curse and get the "Tag You're It" achievement

Step 5: Finish the level to unlock the final two achievements "Along for the Ride" and "All Together Now"



Additional notes: It's very easy to get a kill by throwing if you play the first Pirates level and just throw someone off the edge. That's an instant kill and an instant achievement.

You can have any one character exit the level to finish the last two achievements but you may need to move the other characters along so your position isn't reset. All of these achievements took roughly 5 minutes to get.

In order to win this achievement you'll need four controllers (or some Guitar Hero/Rock Band instruments as they can replace any controllers left).
To explain the best way possible, if we consider each theme level as an Act and each sub-level as a Chapter (e.g. "Cave of Wonders" from Aladdin). You only need to finish a level inside of a Chapter (not the full Chapter) to unlock the achievement.

If you already have four controllers and enough people in your house to help you with this, perfect. Just enjoy playing any level of the game.
But, if you don't have four controllers and instead you have some instruments from Guitar Hero or Rock Band, you can use those to replace the number of missing controllers you need.
In my case, I won my achievement using three controllers and a guitar. You can do it with just one (and three instruments).

Now let's finally talk about the proceedings. After you choose the characters you will use, pick the Chapter "London" from Pirates of the Caribbean as its first level is very short and quicker to end.
With your main character, build the cannon and shoot to the wooden planks to create a bridge. While you do this, let all the other players at the beginning.
The next action can get quicker depending on much controllers are you using, because only the controller's characters can walk. Instruments doesn't have analog sticks and the D-Pads are used to express emotions (such as happy or taunt moves), so they can't walk.
Using only one controller, pick up another character using Y and place him (or throw him) to the lower right corner, somewhere near the chest. Afterwards repeat with the other two characters and then go kill all the enemies across the brigde.
After you do it, use the new cannon to shoot at some wooden planks to lower the exit door. Now you only need to go through the exit door with your main player, let the countdown end and achievement unlocked!
If, by any means, you are having trouble walking to some place of the level because of the distance between you and the other players, just pick them up, one by one, and place them where you think it's the best.
