yep £100 up here too, got married at south queensferry edinburgh, the registry office is a lovely 16c building with a huge bay window overlooking the forth rail bridge...bargain!
The rest of it inc honeymoon etc came to about £2k, we had a sit down meal for about 25 (those who came to the wedding) and a traditional scottish piss up for a further 60 in the evening.
I can honestly say i had everything i wanted, 3 bridesmaids, a convoy of classic minis as wedding cars, and everyone i loved there.
Ended up sliding down the bannister at the hotel in my wedding dress. Friends helped out with cakes, photography etc and we used our wedding music, first dance last dance, music from the meal and put them onto CD's as our favours...as they were such good tunes! put them in a double CD case with a blank CD at the back for people to burn their photos and send them to us as we could not afford the photographers!! ended up with loads!
Got married on a Friday too, which helped with costs!
