My very first cruise was on Royal Caribbean's Song of America in 1982. At the time most everything was included except shore excursions and gratuities. Sodas, beer, wine and a special drink of the day were all included.
The entertainment, food and service was phenomenal. The ship was busy at night with the crew ensuring everything was spotless.
Fast forward to 2015.
Average cabin for the money. Steward was good. Them working on the balcony during our cruise is unfathomable to me.
