I wouldn't call it overcrowded at all. We were there BCV from 10/9-16/18 and we had the leisure pool to ourselves most afternoons. I really mean to ourselves. Later in the week, there would be a few other folks hanging out in the afternoon, but never more than six or so. We strolled over to the clown pool for adult beverages and were always able to grab an umbrella table just in front of the bar--loads of chairs available. The lobby was never overly busy and the buses were full, but not ridiculously so. Further, one morning we had 2 buses to MK and 2 to AK show up at once just after one of each had left--cleared those waiting right out. Finally, we didn't share buses to AK or MK, coming or going.
So, nope, I wouldn't say our stay was overly crowded at all. This was also Columbus Day weekend and Gartner ITXPO began as well.
