I made welcome bags for my guests too. It wasn't a Disney wedding...
I included chocolate (from a local company), pretzels, fancy mustard for dipping pretzels (from local company...in Napa), sparkling water, postcards of the San Francisco Earthquake (we're from the bay area), a map of California Missions (we got married in a Mission), and mints.
My idea was that after traveling, they might want something salty or sweet to eat, and read a bit of local interest.
