We stayed in building 10 before but we were on the ground floor so i can't help with the fireworks question.
We have stayed there a total of 4 times and only had one problem the forst time. It's a nice location, staff is good, we had no pressure to take the tour, big units and close to the parks and shopping.
The only thing my DH does not like is that the pools are shaded against the sun by the buildings surrounding them...i like this as I am not a sun person...To each their own. I loved the 2 bedroom config. as it allowed us to have our own space when we went with friends.
Have fun.
