I don't really understand what you're worried about. Personal safety - no reason for concern. Sharing a guided skiff with an unknown - well, maybe an issue. Look into single angler guided rates or, if you feel up to it, just ask to get dropped off in the morning and picked up in the p.m. Feeling ostracized/alone at a lodge - it's really up to you.
If you can let us know specifically what you're concerned about, it would provide something to go on. Ill be down there, alone, most of May.
BTW, you can do a lot better than a solo lodge trip on Andros. Let us know if you are interested in looking at alternatives.
