Okay..I am not the moderator of this Forum but we are totally going off topic.
I also think there are a variety of reasons that royal weddings have changed recently. First of all, Diana/Charles and Andrew/Sarah were married 30 years ago. The world economy was different and considering that now we are in the midst of a world recession. I think the royal households are more considerate of how the money is spent. Also, royalty has changed a lot (in my opinion) in the last 30 years.....many people no longer hold royal families with "reverence" and as a result, I think that some royals (and their households) try to remain under the radar so to speak. And as a result, many weddings are not as flashy as they might have been.
In addition, let's look at the most recent weddings and the households. Yes, Fred/Mary, Willem/Maxima and Felipe/Letizia all had big weddings....but not to be mean....but the weddings of Joachim/Alexandra/Marie, Cristina/Inaki, Martha/Ari, etc. were not the same and really they shouldn't be. They are not heirs to the throne and while they have a little something, it shouldn't be the same production. An excellent example are the weddings of Anne/Mark, Andrew/Sarah, and Edward/Sophie (also Charles/Camilla)...they are not heirs to the throne so do they really need to get married in St. Paul's? Nope they don't. But I think Sarah/Andrew's was just as lovely. But then Edward/Sophie was really low key...a good reason are the divorces of those mentioned above and the fact Edward wants to just fade as much as possile into the background. Just like Beatrice and Eugenie's wont be the same as Harry's. And Harry's wont be as grand as Williams.
In regards to the most recent royal weddings...I would say Marie and Joachim had a really nice wedding. It wasn't as flashy as his first...but it was his second (and not bad for her first and hopefully only!). Either way....most second hand royal weddings are better than any weddings (in terms of presentation only) that I have attended.
