We could instead target Monday, 6 February to Thursday, 9 February, with Thursday reserved for return travel home.
Logistically, I feel Frankfurt is still a good option with straightforward travel options from Brussels and easier return travel options from Frankfurt. We would likely have to eat some time on Monday for arrival travel. If folks were attending pre-FOSDEM events like CHAOSScon and CentOS Connect, they would have to make plans to arrive earlier. I think it is possible though.
Are there strong objections to not doing it after FOSDEM? If there are no objections, I suggest we lock in dates and location in Wednesday’s Council meeting.
