Ten celebrities will join tour guide Brendan Sheerin for a two-week expedition around the Mediterranean.
Top of the cast list is former entertainer Michael Barrymore, who sets off with friend and Strike It Rich producer Maurice Leonard.
On the journey, Barrymore reportedly falls off a horse and, partly as a result of his painkillers, apparently has a foul-mouthed confrontation with a French waiter.
Among the four other original couples are Big Brother 8 duo Brian Belo with Spencer Smith and Katie Price's make-up artist Gary Cockerill alongside Phil Turner
Also taking part are Ex-WAG Alex Best and Liberal Democrat MP-turned-comedian Lembit Opik, and Lizzie Cundy and model Emma B.
Along the way, Brendan will welcome X Factor legend Wagner, Britain's Got Talent stars Stavros Flatley and controversial horse racing pundit John McCririck and his wife Jenny.
Sandra Dickinson and Helen Lederer will also hop on board later in the series, as will fellow comic Stan Boardman with daughter Andrea.
Celebrity Coach Trip kicks off on Monday, October 10 at 5pm on Channel 4.
