Misuse of choline gas serious effects

I went to this place the weekend of the 19 Jan 24 to celebrate my 8 year old birthday. The warm pool was wheres the kids wanted to be. On Sat morning we went to the warm pool and the kids had fun. At 4pm we went back to the warm pool. When we got in our eyes and throat was burning. The choline gas appeared to be released into the pool. Then my son started coughing and crying that his skin was burning. I didn't realised that thus was the choline gas I wasn't aware of the danger of the gas. When we got home, my skin was swollen on my elbows and legs. My son's private was burnt and the skin on his inner thigh burnt. Other people in our group also affected. I contacted the resort and spoke ro the assistant manager. To date no response. This is serious and needs to be addressed. Don't go to this resort as it is dangerous when the choline gas is misused. We are traumatized and will never go back there. How can this gas cause skin to burn???
