$1.15 doesn't sound bad at all compared to new sawn timber prices up here. I've been collecting reclaim when I can find it for .60/BD FT or less. Yes I have found some good deals. I will have some sanding and resawing costs to some extent, but I figure If It's $1.30/BDFT or less after refinishing, I'm still making out well. It is more work.
I picture it being humid in Belize(Is it?). I'd want to get out of that with some A/C. Your guests might want that comfort after a fun day on the water or at night when they are sleeping. Something to consider.
