am i forgetting anything?

for the e-party, we've already

have a final guest list
finalized the menu
made the favors
gotten disposable cameras for each table
currently working on picture collages

am i forgetting anything? i feel like maybe i am is there something else i could do/get/have for people to occupy them for a four hour party?

maybe get a picture frame thingy that your guests can sign? i got ours from walmart and everyone loved passing it around and writing something on it.. and its something that we can hang up and have for a while.
