Fifteen previous contestants and three newcomers compete in challenges all around the world. However, this season, when Chris rings a bell, the contestants must break into song. If they don't, they are automatically eliminated. By the rules, contestants must sing once in each episode, and Chris may call a "reprise" of the song. Contestants safe from elimination are awarded barf bags full of airline-issued peanuts, continuing the tradition of edible safety items. When a contestant is eliminated, they must take the Drop of Shame, and lose their chance at winning the grand prize of one million dollars.
During the events of Celebrity Manhunt's Total Drama Action Reunion Special, all of the contestants from the first two seasons go to great lengths to prevent being labeled as "has-beens," and being replaced by Chris' new reality concept: Total Drama Dirtbags. Ultimately, after proving themselves through nearly catastrophic means, Chris rescues a group of fifteen (as well as two new faces) to join him on a journey around the world in the third season. Traveling around on the Total Drama Jumbo Jet, the cast participates in new challenges in various countries on six continents with all new drama and challenges awaiting them. Split into three separate teams after the first challenge, the teams work to achieve immunity, as well as a stay in first-class to their next destination. The losing team is then forced to attend a ceremony, where one member is forced to take the Drop of Shame from the plane to wherever they land. The lucky contestant who outlasts the rest of the contestants wins $1,000,000.
There is a total of twenty-six episodes of Total Drama World Tour. However, there is no special for this season.

This is the process in Total Drama World Tour in which a contestant is eliminated; initially, the team that lost the most recent challenge, unless the last challenge happened to be a reward challenge, would vote for a contestant and the one with the most votes against them would be voted off. Since the teams eventually merged, all the contestants began to vote for each other and only the challenge winner received immunity. In the case of a tiebreaker, the two contestants would have to face off until one was eliminated. However, in a special case, both contestants were eliminated due to budget cuts.
The original name of the season was "Total Drama: the Musical." This was brought up in Celebrity Manhunt's Total Drama Action Reunion Special, where Chris and Chef start singing "Total Drama Musical." This was also brought up in Aftermath: Revenge of the Telethon; the screen displayed font which read "TDM Telethon," but this was quickly changed back to "TDWT Telethon."
There isn't a DVD release of Total Drama World Tour for Region 1, but Australia released Volume 1 of the season on DVD on April 3, 2013.
- Eva, Katie, Sadie, Justin, Beth, Trent, and Geoff did not qualify for this season.
- Noah, Tyler, Cody, Courtney, and Heather all made it farther than they did in Total Drama Island.
- Bridgette, Gwen, DJ, and Heather all made it farther than they did in Total Drama Action.
- All of the males who competed on Total Drama Island, but not Total Drama Action, were eliminated in the same order as before.
- This is the only season to have an adult competing in the competition.
- This is the only season to feature three teams instead of two.
- This is the only season in which a female contestant wins in the United States.
- This is also the first season where the winner is not the same in both Canada and the United States.
- This is the only season to feature two confessionals. The first, and more commonly-used one, is in the Jet's lavatory (reminiscent of the original confessional in Total Drama Island). The second one is in the Jet's Cockpit, with Chef or Chris always in the background due to being the co-pilots.
- This is the only season to feature another way of elimination, aside from being voted off, quitting, or being automatically eliminated by a challenge. Chris states that if the contestants do not sing, they will be eliminated.
- However, no one is actually eliminated by this rule, and many people get away with not singing throughout the season.
- This is the first season to take place outside of Canada, although they have returned to Canada four times in Anything Yukon Do, I Can Do Better, Newf Kids on the Rock, Niagara Brawls, and Awwwwww, Drumheller.
- This makes Canada the most-visited country throughout the season, tying with the United States.
- This is the first season in which only one contestant returns after being previously eliminated.
- This is the first season to have tied votes at an elimination ceremony, in both Picnic at Hanging Dork and Chinese Fake-Out.
- This is the first season to feature "fake eliminations," in which Chris has all members of the losing team vote like they regularly would, then reveal the result, but not actually count that person as eliminated.
- This is the first season to feature an odd amount of contestants competing from the start, as Total Drama Island had twenty-two contestants, and Total Drama Action started with fourteen contestants.
- This is the first season in which someone had to leave because of medical problems.
- This is the first season in which a previously eliminated contestant is brought back into the game without being an actual contestant. In this case, Ezekiel was brought back to aid in challenges in I See London... and African Lying Safari.
- This season features the highest amount of irregular eliminations. Only seven contestants were voted off via the normal process.
- This season features the latest merge of a season, with the merge happening in the nineteenth episode.
- This is one of only two seasons to have its main promotional image be a moment from an actual episode, the other being Total Drama Island.
- This is the only season directed by Jennifer Pertsch and Tom McGillis.
- This is the only season where Izzy competes and does not rejoin the game.
