Hi Lily J.
There is no excuse to use any heavy and extremely loud machines at 7:23am!! For any reason!! The two people who use the pool before 9am will understand why the pool might be dirty after the 4th of July!!
But that's not an excuse to use loud heavy machines in an apartment complex at 7:23am. That machine went on for over an hour and woke up the whole apartment complex!! There would be nowhere to live here were you wouldn't hear that loud noise!!
Next time close the pool between reasonable hours like 9am-10am. Close it for maintenance!! You do it all the time!! Why not after a big holiday so people who partied can sleep in!! And the ones who work there butts off all night at a casino (because of the holiday) can sleep in also!! Not to be woken up at 7:23am!!
Seriously!!!
Sincerely,
Vincent M.
