The diplomatic plan
Of course I agree with you that is a big bummer be to distribute the guests for the tables, having to take into account whether there is or not family problems. But on the other hand you don’t want to put at the same table, two family members who are angry, right? Try to make the most diplomatic distribution possible, so that everyone feels good on this special day. For achieving that everyone is well, it is a step towards the success of your party.
Yes! I can tel from my experience that is always has the best results. Someone must take care of children. Hire a cheerleader for this purpose. Children will be served quickly, soup and a dish they like and can go play. They will not have to wait for the whole meal is served, starting to get impatient. Take these small steps and you will see that even the little ones will enjoy it more. Parents certainly will thank you!
