We just went on this excursion last week. It was me and my DH,
DS12, DS9, DD7. About 200 people from the boat went on this
excursion.
They basically put you on your own little area of the beach. There
are Disney Magic people all around you and as long as you STAY
in the area, you will see very little nudity. Several tourists did walk
by (topless only) but the kids barely noticed them.
We wandered down the beach a little ways and there were LOTS
of topless sunbathers everywhere. ALso lots of thongs for BOTH
sexes.
Be prepared to pay an additional $3.00 for your beach umbrella
(they never tell you about this) and also be prepared for LOTS of
locals trying to sell you their wares. Just smile and say "no thank
you". It's really not bad.
The lunch was GREAT !! Ribs or chicken. LOTS Of food. We were
overall VERY pleased with the excursion. I would recommend it !!
HAVE FUN !! Wear LOTS of sunscreen and re-apply OFTEN !!
