I was fortunate to be able to attend EGU26 in Vienna.
There were about 20,000 attendees for the in-person event. That is a big number. It is hard to comprehend how many people it is. It’s a lot. Don’t try to memorise faces, names. Treat everyone as new for the first couple of days, then treat nobody as a new face later.
Read abstracts and not just titles.
Sessions run in parallel. All week. This means there is always going to be something interesting going on somewhere other than where you are right now. Trust your plan.
You can eat during sessions, on the walk between rooms, or just on your break.
It’s easy to get distracted and forget. Nobody is going to ask you whether you have had lunch. So ask yourself!
It’s intense! There’s travel on both sides of the week, so either you choose when to take a break, or it will.
It’s a lot of time spent travelling for a short talk that may or may not be as interesting to you as you expect.
Even if you don’t have time to interact with someone immediately, you will appreciate having the information later when you have the motivation. This is what the conference is for.
These are on average better than 10-minute talks, but may not be as relevant to your field or project.

That way you’ll already know which ones you want to go see, and what you want to ask. Posters take a long time to go through, and you might miss the important ones.
Avoid risking the embarrassment of irresistibly nodding to sleep during a presentation.
See the sun, touch grass, get some fresh air, smell the rain, relax eyes. Anything to connect to the outside.

Find someone to tag along behind for a while.
I tend to be able to remember those talks better in which I have asked a question.
That means people payed attention and understood.
