During a cruise there are numerous activites available at hand to amuse both you and your guests. During the evening there is usually a live show - these can differ from being a full on spectacular stage event, to a smaller intimate show featuring a comedian or entertainer.
During the day there are lots of other options available at hand including art, cooking and dance classes, trivia, movie showings, sports, and parties. The types of shows differ with each cruise line however there is normally a good amount of entertainment options for all ages.
If the ship has a Kids Club there are usually a number of staff on hand to assist and entertain the children.
The choice is really yours! If you would rather sunbake or read a book you can choose to do whatever you want. The idea of a cruise is to ensure everyone is entertained and happy doing what they like. Happy Cruising!
