have a look at www.gocayecaulker.net
there are links there for many of the accommodations on Caye Caulker.
I would suggest that a private cabana would be ideal for your honeymoon...they are actually very affordable, and very beautiful and private!!!
Have a look at www.caulkercabanas.com
I think you might find just what you are looking for!!!
Congratulations!!!
