El Sol Spring this year was in the same location, Sound Garden Hotel. The rooms still have the glass walls for the shower. The hotel was big enough for El Sol Spring, but I cannot imagine how they will fit a regular El Sol in there. I've seen their different rooms and the restaurant. When they want to squeeze 1500 people in there it will be incredibly crowded, even if the crows splits into Bachata and the different Salsa styles. Their biggest conference room is 277 m2, the foyer is a bit bigger, the restaurant and bar arear are rather small. They will also need space for the DJ area and concert. The small space is the reason why I won't go this year. If people report that there was no problem with space, I'll probably attend next year. I actually liked the Katowice venue, but I get why many people disliked it.
