It's easy to accomplish Flores to Dangriga or Caye Caulker in one day....A might harder to accomplish Tulum to San Ignacio in one day. It's a might farther than you expect.
What are you hoping to find in Dangriga? I like that city. It's attractrively dilapidated, but what do you want to DO there? Are you, instead, looking at Placencia, which is a very nice beach community and a place where you can often see Francis Ford Coppola walking around in a sarong? (yes, you read that right)
Smart to avoid BZE for any long period. It's better for your trip. Glad you took that advice.
