We went to buy a Familia becasue as our first caravan going up from 2 washroom-less VW campervans, madam insisted we should have a washroom.
Then Steve at AL talked us out of it and now we have a Puck at considerably less than we would have paid for the Familia.
We use facility sites virtually all the time and even then we keep a Portapotti under the sink when travelling and it's at the bottom of the bed overnight if we don't bother with the awning. Strict agreed rules apply for its use as you can imahine, but that suits us fine. Good luck.
