I went to Vegas for the wedding of a close friend, and while it was an interesting "experience", I'd be disappointed if that was my wedding. It's like a conveyor belt of brides. We were in and out of the wedding chapel in less in 5 mins (seriously). Our bums barely touched the seats. There were several other brides queuing outside as we came out. It definitely didn't feel like a special day - unless your special day consists of being one of many brides. We had a post-wedding meal at one of the restaurants in The Venetian. We had a private alcove (with a heavy curtain that could be drawn across) but every time we went out into the main restaurant (to go to the loo, etc), there were at least 5 other brides dining there. As a guest, it was quite entertaining but it's not what I would have wanted if I was a bride.
The Vegas wedding was an expensive trip and not something I'd repeat. The bride and groom had a DC (PFB) and that made it very difficult for the rest of the wedding party to spent time with them as they seemed to be fully occupied with the DC coping with jetlag/feeding/playing etc. It was a long expensive trip for a 5 minute wedding ceremony and very little time with the bride and groom.
I've previously turned out invites to weddings in Italy and Turkey as I just couldn't afford them. One of them was the wedding of my best friend (at the time) and I was very upset that I couldn't afford to attend. We were close for many years but drifted apart after her wedding.
This year I'm going to a wedding in Bali of another close friend. I was told 9 months in advance which was fine for me but meant that I had to abandon the holiday that I'd been planning for this year. It's too much expense and too much time off work to do both. I've been to Bali before and I'm not a fan, but this is a good friend and I don't want to miss seeing her get married. But I do resent the amount of money and time off work this is costing me, given it means sacrificing the holiday I was planning. Part of me is kicking myself for agreeing to go to the wedding but my flights and hotels are booked and paid for so too late for me to pull out now.
I must admit that I'm sick of people getting married overseas (unless they live there/come from there). I miss local weddings. They felt thoroughly English and it seems that we are losing a little of our 'genteel heritage' and becoming more showy and ostentatious.
