The wedding I went to on Saturday was 'festival' themed, all day from 12-12. We were told it was kid friendly and that there would be a kids' entertainer. Great!
Venue was lovely, in a field with a lake and some woods. The couple getting married are BIG party people and their priority for the day appeared to only be to get absolutely trashed (totally fine), and had spent all their budget on a big stage setup and a couple of (albeit very talented and entertaining) bands.
It was a hot day - there was no shade and no water supply at all. Only two small bars selling beer and cider - the only soft drink options were cans of coke and sprite at £3 a pop. There was a small block of four toilet cubicles with sinks to serve a crowd of 150+ which had ran out of water by 5pm. Lunch was deep fried, super salty stuff with chips - thirst inducing and not substantial at all for a 12 hour day. Of course I took water, suncream, snacks, hat etc. but another kind parent ended up doing a Tesco run (25 min drive away) to get a load more bottled water for all the kids.
I guess they nailed the festival theme! But as a wedding touted as kid friendly, not great? If I'm being invited to an all day wedding at a rural venue in an open field I would have expected a water supply at least? Also they've had 2+ years to organise - it was postponed from 2020.
