Cruise issues

I recently returned from my  10 day cruise on the Gem.....definitely not uneventful.First let me say that the crew on this ship busted there a**es to make things right. We arrived and boarded without any incident. I noticed a lot of younger toddler age children running about coughing and sneezing at the buffet. The crew was at the entrance at all time spraying hands to make sure hands were clean..I came down with a cold 2 days later.I found the  ships gym to be very small and overcrowded.On the 2 day we ventured into the adult hot tub that was far from hot. On the day after we left San Juan we noticed that the crew was serving food at the buffet instead of helping yourself..They even poured your coffee.....Later in the day the captain made an anouncment that people were reporting a gastro intestinal infection was going around and that "a handful of people" were sick.Also we notice that the pools was drained and cleaned several times We decided to not eat at the buffet and drink only bottled water. We got off the ship at St Thomas and toured St Johns..The next day we were denied port at St Martin because of the outbreak. The Captain announced that we would have a day at sea and reminded all to be vigilant with hand washing. We were never compensated for missing a port..People who reported an illness were quarantine to there room for the rest of the cruise. This illness was definite downplayed...In speaking with several other passengers one who claimed to be a swimming pool expert we came to a conclusion that there was an issue with the swimming pools and hot tubs. We did not enter a pool or hot tub. We also had several issues with the toilet.It was corrected and reoccurring.(wouldn't flush)It was addressed in a timely manner

  When I returned I found that this was not the first bout with GI issues on this ship. The "handful" of sick passengers turned out to be 130...More than a handful....I don't know what the answer is to this issue...One problem is the unsupervised children spreading germs all about the ship.

  Service in the general dining was slow. The food was just OK and the staff was overworked and short...I don't think I will be going on another cruise for a while
