Regarding the lack of staff...here's our theory...
With more and more people subscribing to a drink package, the cruise lines (not Celebrity specific) are not hiring the additional bartenders and servers...thus saving $$ for lack of service to serve drinks!! We were on EDGE pre covid and found people 3 and 4 deep around the bars begging for a bartender...who were running around nonstop!! The fewer servers/bartenders, the fewer drinks, the more $$ in the company's pockets!!
