Can anyone point me the right direction for information on getting from Cancun to Belize City by bus. Are there any websites with times etc.

Thanks

www.ticketbus.com.mx will give you the times from Cancun to Chetumal, but you would do best to head Playa straight from the airport and change to another to Chetumal. Otherwise, you backtrack to Cancun. Those airport buses are past the far end of the main terminal, not the one for charters. You turn right outside the door. From Chetumal there will be buses to Belize City and an early shuttle to Cayo and Flores.
