I love royalty threads. You guys have such great perspectives, both on the current people and the historical ones.
One thing I haven't seen directly mentioned--I think even if William and Kate wanted to/would've been okay with inviting Fergie, this is one wedding where I would never tell the HC, "It's
your wedding! Stand up for yourself against the relative paying for it!"

I am guessing the Queen had final say over the guest list and if she didn't want Fergie in attendance, it wasn't happening. Not that I'm on either team (Team Queen?) but I think it's kind of fun to imagine all the wedding-planning advice we would
not expect this particular couple to abide by... "Oh, you don't want the fuss of a big wedding? Grow a spine, elope to Vegas!" (Gretna Green?)
