Cancun to Corozal

Want to travel from Cancun to Corozal by bus, but don't wish to arrive in Corozal at 0600. Is it true that there are other buses than ADO, that leave Cancun early afternoon and arrive early evening? Any info on a web site or actual experience would be appreciated. Leaving Fl on 2/28/12. Thanks, Cal

you can take the ADO bus to Chetumal (buses run almost every hour or so) and from three a local bus to the border.

I would like to know what you decided to do?  Did you take the ADO bus to Chetumal ?  Then a local bus to the border?  After you go through customs, how did you travel to Corozal?  I plan to make that same trip next month and would like to know options. Thanks!
