Unless your guests are foodies/all a similar type of person or not big drinkers, don’t worry so much about the food because there will always be people who don’t appreciate good food, ‘don’t eat foreign rot’, ‘it’s not like this at Prezzos’ etc. I’ve been to maybe 50 weddings in the last ten years, budget to £50k+ dos and I can only remember the food from 2. Have what you want for you, but don’t do it for the guests/accept they are not al going to be thrilled by it.
Like they say, no one remembers the wine, they only remember if you run out! It’s very true.
As someone above mentioned, the very best thing I’ve seen is a basket of cheap flip-flops for ladies. Primark do them for 80p.
Also little basket in the toilets with hairspray, body spray, plasters etc.
This only applies if your guests are drinkers - Anything you can do to stop people getting smashed before the speeches is a good idea so if you’re not having canapaes or eating on arrival, maybe a piece of brownie or cupcake exiting the church. If it’s a winter wedding flasks of hot choc or weak mulled wine at the church is lovely. Most churches will have a tea urn or facility to can access. I also suggest lots of water on tables and bottles/jugs of water out later for people to help themselves.
In terms of transport, I’ve been ferried from church to venue by bus and had to drive to church then the venue and both are fine. I would only consider paying for a bus if lots of people live walking distance of the church so they don’t have to even get in their car or collect it the next day. If they’re driving to church, may as well drive on to reception.
