SGU, Ross, and AUC are all fine schools. I hear Saba is getting up there. SGU has better clinical placement but AUC's island is a lot nicer (though very expensive to live on.)
Back to the original point of this thread, I'm tempted to try at least one more time to get into a DO school and adding USMD schools next year to broaden my application pool. However, doing so would be another year wasted.
The only problem I have with going to the Caribbean is that my wife wouldn't be able to work (RN) and I don't think we can financially live on just student loans with the obligations that would remain here.
My numbers and, subsequently, competitiveness increase with each semester, and it's getting to the point where it might be foolish and unnecessary to head to the Caribbean, particularly with my SGPA being above a 3.50 after this academic year. If I decide to retake the MCAT, I very well could be admitted through WVSOM's ED program regardless of this year's outcome.
