We did a BTB Nov 13-27.
Ship: The Gem is a medium sized ship. We prefer this size rather than the Getaway class ships which are often filled with too many kids.
Cabin:Our starboard mid ship balcony cabin was good size for us - I would not recommend it for three people. Bathroom was too small, so I used the men's rooms on the ship.
We explored Old San Juan and the San Christobal Fotress on our own. A lot of walking.
Walked around on our own.
Love the beach.
Rained all day.
Drinks on a train.
