I think you're plan is good in theory but the reality of it, isn't that practical. Like, If you go to SAB in the middle of the day, how will you get your suits? Do you want to lug them around in a separate bag all day? It sounds like a long day already, rope dropping EP, swimming, and
MNSSHP, thats a long day, coupled with a late arrival the night before and switching resorts, it just doesn't seem worth it for a couple of beers/wine and breakfast. If SSR is a possibility arrival night then just go with that.
