Distinguish the venue from the wider park
Pinellas County publishes information for Walsingham Park. Use the details for your actual booking and ask which bathrooms are available to the group. Do not assume that every nearby amenity is included or that a reservation automatically permits supplemental rental equipment.
Agree a position with the responsible contact
Describe where people gather and how the supplier reaches the proposed facilities. Include washing, accessible needs and the occupied timetable. Confirm the arrival and removal arrangements with the venue representative before accepting an equipment proposal for the occasion.
