We missed a few photos as well. I know some people make a list of photos that are 'must haves' and give it to their photographer in advance to make sure they get them. No regrets otherwise.
A few things I am so happy we did was get our own limo. After our small ceremony, our reception was in a different town. My husband and I got a little limo for just the two of us. We packed snacks and champagne and had a wonder hour just to ourselves talking about the ceremony and relaxing a bit before the reception.
We also got ice cream together. It was so much fun just hanging out around town in our wedding outfits and doing everyday things like getting ice cream and going for a walk.
Similar thing - I wish I didn't just think about the photos I suddenly wanted and then felt bad asking... And just asked! We hired photographers for a reason!
