London Gathering in June?

I’m going to be in London, then Lisbon in June. I have to book my ticket pronto, but I thought, hm, should I come in a day early and have a gathering with my lovely London (and vicinity) friends? I will be arriving on the 10th (prolly around midday, jet lagged) and have to work on the 11-13th. Should I come in a day early? Does someone feel energetic and want to organize something? Let me know SOONEST!

After London I’m on to Lisbon for an Elearning Conference, then KM4Dev gathering in Almada, then a few days of VACATION!!!
