I've just read a lot more of this thread...
I've done plenty of weddings where the couple go away, get married and then have the 'wedding' for friends and family at another time. Doing it on your first wedding anniversary is both good and bad - if none of your guests know you got married, that's great! If they do know, then it is seen as more of a 'party' than a wedding.
Ryanairbride - I see its your wedding - you mention having a braii - are you South African? If so (in the nicest possible way) this changes a lot of the etiquette - if there is to be a lot of SAs there, to them it may be more normal to them to have to pay something. Also, in a lot of countries it isn't the done thing to have a pay bar.
In terms of licensing for the drinks, if it's a location where they hold events regularly they will have a licence. If they don't normally hold events, it will need to be applied for, but the venue should do this for you. They may need to get a one off licence which they would probably charge you for.
A 'pot' next to a drinks table is a good way of doing it for this type of 'do' if you are buying your own alcohol in - there's no need for the venue to have anything to do with it then.
Do make sure you check with the venue if they will be charging you any corkage for your alcohol (most places charge between £7 and £15 per bottle for wine, more for champagne and spirits)
Please do be careful though if you do try to charge guests or alcohol you have brought in if they venue have agreed to no corkage charge, if they find out you are charging your guests, they may backtrack and charge your corkage, which they are within their rights to do,
Also check:
Will the venue staff man the bar
Will the venue staff provide the glassware
Is there somewhere at your location for glasses to be washed / staff to do it
Where I worked there was an 'off site' barn type thing where we did events and originally there was no water there. Or loo! That's changed now though.
Just a few points there for you to consider.
If you have any more questions , just let me know. I've planned almost (or just over - I stopped counting!) 1000 weddings in my career so have seen a lot!
