Certain graduates of a class are donating money to place an ad in a booklet celebrating s school’s centennial. Their names will be placed in the ad. The intent of the ad (and sale of the booklet) is to raise money for the school. We have a choice between a one page ad and a two page “centerfold” ad. Some members of this group (and I) believe that the two page ad is somewhat ostentatious and belies the intent of the donation.
My problem is to communicate to the rest of the group using diplomatic language that the two page ad tends to be ostentatious. Is there a better word or phrase for “somewhat ostentatious”? Dictionary.com gives several synonyms – none of which seem to fit a convincing yet diplomatic statement.
