What's the difference between a flushing portable toilet and a deluxe unit?
We're getting married next spring in my parents' backyard with 140 guests. The party will run about six hours with a catered dinner and an open bar. I'm looking at renting portable toilets and see both a deluxe unit and a flushing portable toilet listed. The descriptions both mention a flushing toilet and a sink, but the prices are different. The rental company says both need to be on level ground near the driveway for the vacuum truck to reach. I want to know what the actual difference is between these two types. Is one more comfortable or easier to maintain for a wedding? Should I consider one over the other for guest experience?
