Unfortunately it's not always up to WM or other companies to allow boon-docking or not.
We just got back from Florida ourselves and were told by WM staff in a bunch of places 'sorry, not allowed anymore'.
Except it wasn't once the WM that had disallowed it, at 2 places it was the management of the plaza and 3 others the City council that had passed by-laws to prohibit overnight parking.
In 1 spot (Naples, FL) we were told the plaza had gotten lots of complaints about RV's parking overnight in a ritzy area so they banned it.
In another there had been a few close calls with RV's being targeted by 'less than desirable' citizens in the middle of the night and the Sheriff's Dept. had asked for the ban as a crime prevention measure.
Another sad sign of the times.
