My Dh and I got married this past July, we had a buffet style reception as well, what we did was theme each table with a different character. For example we were the Cinderella and Prince Charming table, we had a mickey and minnie table, we had the donald and daisy table, and so forth. Our actualy place card holders we made our own wedding cds ( which were our favors as well), with our favorite songs and favorite Disney songs, and the cover was the picture of the character table they were sitting at. Each table had a stand with the same picture in it. Something else we thought was really cute,was they have chocolate place cards which they write the names and tables where every one is sitting, then they also can double as your wedding favors. I think it is really important with a reception to have a sitting arrangement so 20 people are not all at one table, or 1 person is not feelig left at sitting by themselves at a table. Happy Planning!
