Start with the specific park location
Pinellas County publishes Walsingham Park information. Check the space actually reserved and ask the responsible contact which bathrooms the group can use. Do not infer unrestricted supplier access or permission for extra facilities simply because the park has rental amenities.
Choose according to the remaining need
Explain staff and guest hours, accessible requirements and washing. Compare the proposed cabin or trailer with the approved position and any connections. Confirm arrival, attention and pickup windows as part of the arrangement, not as an assumption after equipment is ordered.
