In 3 weeks and 2 days no less - for a 3-day weekend but any amount of time in Paris is fine with me.
And all this is thanks to Asali who convinced me it's no point in delaying these kinds of things, who will be there at the same time so I'll meet up with her, and who obviously knows when is the right time to prompt people into such undertakings as I found a return plane ticket for quite a reasonable amount of money (and a wonderful hotel to stay in too, at least it seems so from their site).
I'll be sure to take a lot of photos and describe in detail the fun everyone will have. :)
Until then, some pics from the last time I was there:
