Pool water

Hi Blue Marlin Hotel, I was a guest at your hotel, we arrived at the hotel on the 23rd and I was in room 9. I was happy with everything till my husband and son got sick on Christmas day first it was my son 9 years old in morning, woke up with a sore tummy, vomting and had diarrhoea (he has been swimming since we arrived) and could not eat anything ,after breakfast my husband decided to go swim 12:30 we all went for Christmas lunch that they prepared for the guests immediately after he was done eating he did not feel ok and went back to the room to take a nap while we were still sitting outside my husband was trying so hard to survive as he was vomting, nausea and diarrhoea ( bad stomach cramps) later when we got to the room we find him sleeping and he told us what his been though and we all thought it was the hotel food but than on the 26th we all left for Ushaka marine we did not eat from the hotel (no one was sick).Friday the 27th I told my daugther let swim we cant come here and not swim as we leaving tomorrow, the whole day we swam but did not eat any food from the Hotel, guess what? me and my daugther did not sleep that night same symptoms as my husband I felt like was was gone die, we woke up very early that morning by 7:30 we were all done leaving the hotel I didn't say anything to the reception ladies as I was not feeling good ( I am sure that we are not the only people who got sick from the pool water). PLEASE MAKE SURE YOU CHECK THE CHEMICALS USED TO CLEAN THE POOL BECAUSE ONE DAY SOMEONE IS GONE DIE FROM THE POOL WATER.( just worried about some other guest who was pregnant and was swimming with us😥I feel so sorry for her if she got those stomach cramps😓) Yes we all went to the DR Sunday morning and he confirmed that its the pool water and not food poison
