Use the park-rental information first
Coral Gables publishes park-rental and facility-use guidance. Review the actual location and reservation with its responsible contact. Ask which bathrooms are included and how supplemental equipment is handled; a sanitation quote is separate from permission to use or equip a public space.
Build only the missing parts
Explain the guest and staff timetable, washing needs and accessible approach. Compare equipment against those gaps rather than adding an unexplained package. Review supplier access and removal alongside the facilities so each part of the proposed setup has an agreed place and purpose.
