There has been many dance type parties in many places during the evenings. Theme nights (inside) and general deck parties most nights.
Buy the fun pass before boarding. It's $80 and you get $140 to spend in the Hall of games, pool hall and robotron. The "rides" range from $6 to $12. Most are $10 & $12 per experience for a 3 to 5 minute "ride". There have been almost no lines every time my son has gone.
