This can get a bit tricky especially if you have a large guest list or unfortunately have feuding family members or divorced parents that are not on good speaking terms:-( I found this website through Brides Magazine and thought it was a little bit like playing musical chairs! I logged onto this site to experiment with a trial run and found it relatively simple and straight forward to understand. You can add tables of various styles and sizes and move them anywhere on the screen. You can also drag and drop guest names as easy as can be and save several versions to see which one works best. Additionally, you can import a guest list from an Excel or Word file. This site can be used for planning the seating arrangement for any party or celebration!
There is a $20 fee for this service and it is good for 6 months. There is a money back guarantee within 7 days if you are not satisfied. I think it is well worth the cost for the convenience. Good luck!
