What Honeyroar said.
Be realistic about what you think you can afford to spend, then prioritise what is important to you
You'll get all sorts of opposing views, the more replies you get.
Also, things like the size of your families and the numbers of friends you have, come in to it.
I went to a wedding once where 11 of us (incl B&G) went to the ceremony and then just to a meal in a smallish restaurant (not booked as a wedding, just a meal, so no inflation of prices), then they had a party in a hall in the evening. Lovely
I've been to two different weddings that were on campsites.
I've been to weddings in grand stately homes.
I've been to receptions in a school hall, a Church hall, some parish rooms, in social clubs and in posh hotels.
I've been at weddings where various guests donated their talents (cakes, photography, flower arranging, driving their own car, etc).
there is no correlation between the cost of the wedding and how nice it is.
Decide what is important to you two , have some consideration for guests' comfort, and stick to what you can afford.
