I've got a 20 floor ride at home and 45 at work each day and will never get in a 100 pct packed elevator again -- not because being stuck was so lousy -- have had worse experiences on the tarmac at ewr -- but because it would be with a bunch of let's say less level headed folks. and no pre ride champagne!
great group to be 'stuck' with and our continental hosts in the elevator were nothing but professional.
