A strong suggestion that should you choose to accept the bid which UA offers, that you confine your group to those for whom you are paying.

Nothing breaks up friends and family better than group travel situations where you are advancing the cash for the ticket, someone sends in their payment late, cancels and wants you to issue a cash discount, needs a seat you can't obtain and so on.

As to the people in your group, make sure that they get a clear and concise email explaining exactly what they are and are not getting. Those who should be thanking you for your generosity can turn into your worst nightmare when it turns out that UA does not cater their left-handed Asian-vegetarian appetizer.

OTOH, 5% of 14 tickets to FCO is a nice chunk of change.
