Performances are usually a net negative for me, so guess that makes it pretty clear. Sibenik got it right imo, 30 mins or so and only top notch artists, and say 2 (?) hours of the band.
The band was absolutely top notch in the performance they gave. The venue of old town square was a perfect setting. That is something very hard for 90% of the congresses to match. Sibenik got many things right including good dancing and the music. The only knock (major) I have is that one is literally locked up in a commercial resort for 4/5 days. I would prefer if it had more dancers (I think any given time there were 300–400 salsa dancers in the night). But that is all nitpicking.
You were there?
