We got married in the Saddleworth Hotel, the main selling point being that they specialized in weddings and you had sole use of the venue. It was perfect in every way and the owner is fastidious over the smallest detail.
We paid £1000 Hire
Then i think about £86 per day guest (however that included a 5 course 3 AA rosette restaurant meal, a rolls royce silver phantom drop top wedding car, DJ, flowers, reception drinks etc)
and then £14 per evening guest. We had about 35 day and 35 extra for the evening which worked well as you got chance to actually socialise with those you invited as oppose to some weddings which are so huge you get to see the B&G for maybe 30 seconds.
That was about £5K all in, plus £750 for hand made dress, £150 suit hire for gents and we made the invites and had a friend as photographer who was about £600 for the day including electronic copies of hundreds and hundreds of pictures.
Just over £2K on the honeymoon (saved over £1500 by booking the cheapest room then bunged the woman on the front desk $100 dollars to upgrade us which she willingly did)
I would have happily had a BBQ in the garden but its all about the wife at the end of the day and its her day to feel special.
Most importantly save and pay for it so you can start married life debt free, plus pay off debts other than mortgage if you have one first. If you havent got it dont spend it as the stress at the start of married life wont be worth it
