Excursions in Nassau

[DizMagic]

We are heading on a short 3 day cruise in May. we are interested in 2 excursions our day in Nassau and wondered if anyone has done either / both of these and could comment. Our specific question is - can we do both of these in one day. A more general question is what did you think of these.
