Yeah I'd much rather spend that extra week per quarter on vacation instead, and I'd probably get about as much done. My job just does not require 1 week of solid meetings per quarter.

What makes you think these are "solid meetings"?

Basically whatever they are, half meetings half forced vacation, I'd rather just have real vacation.

They can be none of that but regular work, just in person except you have the time to bind in person and decide (or not) to share time together after work.

My team is split across several countries, I don't need to see my teammates in person on a daily basis but I like to have the chance to see them once or twice a year and also tackle specific problems, run some workshop together during hackathons and participate in a teambuilding event.

The current company I'm working for, VC funded startup, does two company wide offsites per year, 5 days (one work week) each. Then another department wide offsite for another 5 days in another quarter, then the final quarter is a team-wide one that is up to each individual team to schedule and intended to last 4-5 days. So that tracks pretty closely.

TBH I feel like it's just a little much, but not much more than a little much. In other words, I think probably two weeks (10 full days) is probably a good minimum because I do see some value in seeing the team once or twice a year in person. So somewhere between 10-20 full days is probably the sweet spot for me.
