If not, it would have been probably the IETF in San Jose, quite some time ago. Attendance numbers for the last 14 meetings are trivially available from the command-line (and figuring that out was about two minutes' work following a search for "ietf 87 attendance"). Berlin was the best-attended meeting in that period. And also the meeting with the most unexpectedly high ambient temperatures, although I have no science to back up that claim, just recurring nightmares.
