I would check with your resort. For example, I was told that they won't do a seated dinner for more than 20 guests. Our dinner at one of the restaurants is free and we will all sit in the same section, so it will be semi-private.
I didn't see the point in spending and extra $95 pp for food and alcohol. As a compromise, we are having private hors d'oeuvres after the wedding, before dinner, in the garden so our guests have something to do while we are taking pictures.
