Pam, I can hardly believe it myself -- well, yes, I can believe it since my American Airlines e-ticket is in my hand. No sister this time, nor my husband (who hates airplanes); probably I'll be by myself, unless one of my "girlfriends" decides to join me. I'm okay with solo travel; true, no buddy to explore with, but it does provide the ultimate in freedom of choice what to do & when to do it. Going in May sounds okay to me: low-season price break but not too much rain & ahead of hurricane season.
Not Belizean Shores this time; I love that place, but by myself, less space with a lower price makes sense. I'm checking into Mata Rocks and Banana Beach, since walking to town sounds appealing.
If Coco Beach is just south of Belizean Shores, then it could be the construction project shown in one of my photos, entitled "Cement Pour". I don't remember that project's name right now. I think it's being done by the same owners as Belizean shores. I do plan to water taxi or golf cart up north one day, so I'll have a look & check it out -- with photo(s) of course!
