Your wedding sounds absolutely lovely! Love the idea of a photo wall! The puddings sound perfect 🤩
Agree re formal photos, I didn’t have many and wish I had some of my close extended fam and friends. It’s lovely to see them and their outfits given all the effort, and look back at them. The candid photos didn’t capture everyone which was such a shame. Or you get many drunk photos.
With respect to the buffet which sounds lovely, I would be concerned about food running out or some people taking much more than others. You may need some kind of system going to ensure people don’t rush the table. I had a manned buffet which was topped up, so would think about how you can ensure everyone is fed. I like the idea of a late snack, especially as people will be dancing and drinking. Helps to soak up the booze too!
As someone with dietary requirements, it’s nice to make it very clear for people with allergens etc where their food is, it’s embarrassing enough having to trouble people for this info at events; or having non allergy people eating up the food that is set aside for those with special diets.
Re the horse, could you forgo the cart and just walk with the horse whilst wearing wellies. Get some lovely pics? Not a fan of animals being used for labour. Alternatively, you could rock up in a VW beetle or tractor - cute pics & rain won’t ruin the day.
Re the dj, your brothers partner may well like to have a day off as I imagine he prob gets asked to dj at weddings/events all the time? He could still do a playlist for you if he wants to help out, but at least he can just enjoy himself. Just a thought.
Other points I can think of:
Do you have somewhere for gifts?
Are you having a cake? I read a tip that cake after getting hitched with sparkly is a nice way to ensure the cake is eaten & it helps line peoples tummy’s. People don’t tend to eat cake after dessert, it’s too much. Plus great pics 😊
You could get some shawls or blankets for warmth?
Maybe some flip flops for dancing.
Is the lighting in the barn okay for photos? Have you designated someone to deal with issues on the day so they don’t bother you?
Will you be feeding/watering the band & photographer?
You mentioned a pool - I would make sure no one had access to that, especially with kids and people drinking.
Is there anything special you and your partner love which you could incorporate into the wedding?
