I guess if you have the money available, then why not?
DD1 had a fantastic wedding in London, and although it was expensive, the guests still refer to it many years later! Church ceremony with bridesmaids, flowers, cars, then London bus ride to the venue, sipping champagne en route. Wedding breakfast, cake, evening buffet, jazz band. A Joyous occasion, smiling faces, everyone still friends and the couple still very much in love!
It was around the time of Prince William's and Catherine's wedding, so not as glamorous as theirs, but well coordinated by my DH who had contacts in the London theatre world for lighting, staging and music. Our DD was youngish and full of her own wedding dreams without wanting to be showy.
Hen do and stag do were fairly normal events.
No one went into debt, and their flat was mortgage free anyway.
