For me honestly, it was always:


 * Summer 2005: Chris leaves Larry on the island when location scouting for the show.


 * June-August 2007: Total Drama Island and Total Drama Action occur (original cast is 16)


 * February-April 2008: Total Drama World Tour (original cast is 17 except Cody, who turns it near the end)


 * June 2008: Total Drama: Revenge of the Island (original cast are all 17; Revenge are all 16)


 * June-July 2009: Total Drama: All-Stars (original cast are all 18; Revenge are all 17)


 * August 2009: Total Drama: Pahkitew Island (original cast are all 18; Revenge are all 17; Pahkitew are all 16)


 * Between August and October 2009: Owen, Noah, and Geoff have birthdays (so does Junior and probably some other contestants but that's not relevant here)


 * Late October 2009-January 2010: The Ridonculous Race (some original cast 19 and some 18; Revenge are 17 or 18; Pahkitew are 16 or 17; RR are misc. ages)

Then: Chris left Larry on the island three years before Revenge of the Island, Chris is 30 in Pahkitew Island, Owen, Noah, and Geoff's ages make sense, Leonard's age makes sense, and there's really no continuity problems. The timeline is there, you've just got to look :)
