Hi… we go most years to Womad. To eat 3 meals a day is pretty pricey, usually around £15 for meal with drink, especially once factor in kids too. We take porridge pots that just need hot water (so little stove to heat water/kettle).
Showers are always busy first thing, so sometimes good to come back during the day, to refresh for evening.
Generally the toilets arent too bad -last year there were she wee toilets as well as usual porta loos, plus sawdust toilets on campsite which we preferred. Take hand sanitiser in case it runs low. We usually have one of us with la di dah loos so can take kids in (although price is much more this year!)
The phone signal can be a bit patchy so if meeting up with people, old school location and time works better sometimes. Also, always need to recharge phone at somepoint, my husband takes a recharger with him.
Have something distinctive to put on your tent - once there are several up around yours it can get confusing.. we use coloured bunting, then navigate by flags or items on poles to find tent again!
overall it is relaxed and people are friendly. We often have a loose plan (with lanyard programme) and then go to whichever stages sound good if unsure!
Also if you get a chance to do workshops, or taste the world, just adds something different, as does physics pavillion and poetry! If you are bringing kids, there is loads to do at the world of children, activities rotate through so good to check timings.
enjoy!! We are heading there tomorrow!
