I got 3/4 of the way down the aisle (after organising a 3yr old, 7yr old & 9yr old perfectly to walk before me... in time... perfectly apart) just to where everyone could see me (it was an outdoor wedding so I just came through the garden in front of everyone) & had DH's grandmother yell 'Stop the music, start again, start again!' because MIL was late and was still arriving
F%@#ing MIL is always late... and its always about her!!! I thought my mum was going to murder her
So we had to turn around, start the music & start again... and of course the kids didn't do so well the second time

We were married in the vineyards & after a really mild week of weather we copped a 43 degree day - and our wedding was at 9.30am, we had a champagne breakfast!!!
Poor DH wore a white suit by the pool at the resort - he hates all of our wedding photos because you can see the sweat all over him & his clothes in every one!

Not much you can do about weather though... and I agree with BG - you can't sweat the small stuff... some things are beyond your control (Unless of course, you have a MIL like mine & I really should've known )

Best of luck hun - it will be fabulous
