Hi Barbara K.,
About a month or two ago, someone contacted me about the LD buses to Flores. She said that she had contacted LD by email (address obtained from the LD site) and was informed by email that LD no longer operated buses between Flores & Belize City.
However, the route still appears on LD sites, and I haven't heard from any other travellers that the buses are not operating.
I haven't contacted the agent yet. The agent I know in Belize City is Mundo Maya Travel in the Caye Caulker water taxi terminal. Email: firstname.lastname@example.org
They may have changed their name recently.
Also, last year Fuente del Norte began operating between Flores and Belize City, and I think San Juan still operate. Details on BelizeBus. And I've heard of a bus that departs BC at 3 am, but I haven't got any more details about that one.
