I promised to report back on Mambo Italiano Rome (Dancehouse Events), but frankly, I'm somewhat torn as to what my verdict is. On the plus side: everything was absolutely gorgeous. Also, the weather... But that's to be expected in May-June in Italy, I guess... (btw., the event will be held end of March next year). The main venue had a garden with a fountain and tables arranged around it, so if you didn't feel like dancing, going out and socializing there was a great alternative (sometimes you could even get snacks and drinks there, which were included in the price). My main problem was that I didn't feel like dancing a lot

and I'm not sure this had anything to do with the organization or just my mood. On the organizational part I'de say there might have been a bit too much of a gender disbalance and maybe overall the event would have benefitted from being slightly less packed. Moreover, it was extremely hot - I guess not much could have been done about that in a historical building like that (some rooms had better AC than others), but maybe some large fans would have been nice. I was a bit surprised as I didn't find the overall level to be crazy high as I was expecting from a Dancehouse Event (this was my first), but friends who've been to a few others before confirmed that it's usually somewhat higher. Except for Friday, where music and sound were poor during most of the night, I thought music was overall good (I attended all parties, so Thu-Sun, but didn't go to any of the afternoon socials). Oh, the bar was pretty amazing, which is really nice. Water wasn't always available, but most of the time I got some when I was looking for it. Everything ran pretty smoothly, there were hardly any delays, the schedule was fairly accommodating to everyone's needs. The girls working the registration desk were super sweet and helpful if you needed anything.
I guess what really bothered me about this event is something that is not controlled by the promoter in any way, namely the fact that much of it felt like a social media spectacle. People were constantly recording anything and everything and it felt like that completely took over the dynamics on the dance floor as well. Hence I am so unsure of how I would objectively rate this event. Given that Rome was extremely expensive I'd probably look into some other Italian congresses next year.
