Gypsy's right...we stayed in a Big 4 at Swan Hill and they had 4 family bathrooms that all had a baby bath, bath, shower & toilet all in one room which made it heaps easier getting them all showered without EVERYTHING getting wet!!!!!
PJ - how is bathing a baby in a trough any different to washing their dirty clothes (and potentially nappies). Sounds like a silly rule to me. Because we don't stay in caravan parks we just used the camp shower (battery/car powered) - I held her and washed her, and then once she was showered I passed her out to the towel holder to dry and dress while I then showered myself. Both my girls love playing in water.
YCF....we don't make the rules at the CPs...we just obey them and as you say....many of them are silly rules but you can bet your bottom dollar that someone somewhere did something that resulted in many of these rules being made in the first place.
The worst day camping still beats the best day working
