Identify the reason for an upgrade
If you prefer flushing, an internal sink or a trailer, explain that feature requirement. Ask what the proposed model actually includes and what space or connections it needs. A premium-sounding category should not substitute for a practical equipment comparison.
Review the venue’s occupied period
Include setup and cleanup as well as public hours. Discuss accessible routes, separate washing and existing bathrooms with the organiser. Confirm supplier entry and collection with the property contact before treating the enquiry as a settled rental plan.
