We have an A126, with the cassette toilet. We use ours every trip, just more convenient than making the walk at night.
The cassette has gotten us through the typical weekend stay with no issues.
Emptying it is easy. Remove the cassette (waste tank) and roll it to the bath house and empty in a toilet. The tank has wheels.
Clean up after a trip includes emptying before going home. Then filling and rinsing twice after getting home. Easy.
