I'm from California, DH is from Kansas, we live in Washington DC area. We didn't do favors. Neither we, nor our families, thought it was tacky that we didn't do them.
I've been to lots of weddings. I've gotten my seeds, cameras, picture frames, chocolate, bubbles, etc. The best stuff is something you can eat. The rest is just stuff that I feel bad throwing away but has no practicle use in my life.
Save the $100 in favors. Buy yourself a nice dinner on your honeymoon.
Or, donate the $100 to a charity with a list of the names of your guests. I went to a wedding that did that and I thought it was pretty classy.
