The pool volleyball at CN is scheduled for 2PM daily except on very rare occasions.
In March of this year the activities schedule had water aquacise scheduled daily at 11AM with the exception of Tuesday, though in practice I believe the visiting exercise instructor may influence what actually takes place.
I always spend a LOT of time floating around the pool on my floatie trying to hold onto my rum drink while socializing ....... I always go home with sore shoulders from this activity so does that count???
I have been a visiting fitness instructor and have been to CSA, CTI and CSS. And there is always pool volleyball, water aerobics (almost everyday) and occasionally, some of the guest bring water games (beer pong, 3 man, cards, etc)!!! No need to worry! Plenty to do!
