No, sorry, but I doubt I have enough masochism (enthusiasm) to do this again... traveling to different venues, checking them out, making arrangements. I'm only doing this now because there was no alternative, but now I see that Moscow and Moldova have venues available from Merlin... if you don't want to consider this option, no one is forcing you. I would be happy to just come as a regular attendee and simply relax without any organizational problems or obligations.
What's the problem? You're saying that we're not interested in the May dates anymore, but we are interested in July 31st - August 7th. Two more cities are being considered as potential venues. The decision will be made, tentatively, by January-February. Why rush things? I highly doubt that they will have August booked by December - the Moscow venues only recently opened sales for the New Year holidays, and no one has even posted information about prices for the rest of 2021 yet.
You've just set your sights on the May dates, but no one is particularly interested in them anymore. Those who work for a company or abroad don't even have May holidays. Only those who work in the public sector are affected - but even they can take the same week off as vacation.
