OK so it turns out the register office I formerly suggested was 'grotty' now only has two slots available, and even those are squeezing us in. And I checked it on Google Street View and it's not actually that grotty at all - or better than I remember.
I have to let them know today which is better (and neither is ideal):
10.15am, at which we get married in jeans and then go back to the venue and relax and get ready
11.45 am, at which we get married in wedding attire and then go back to the farm and wait for guests to arrive before we do the bit up on the hill
I need to let them know by 4pm. Help! Which is better? J still doesn't care if it's the day before but I do. Will I care if I do it in jeans? Help!
