HELEN'S ANSWER: It is always lovely to receive a hostess gift. Maybe you could drop it off after the party to the hostess. You always hear about gifts getting lost at a restaurant or a private club because no one knows where to store them. That is why I always discourage taking gifts (even wedding gifts) somewhere they could be misplaced.
GUEST'S ANSWER: Kathy Walker, local volunteer and community leader: How thoughtful of you to want to give the hostess a gift. If she lives within your vicinity, it would be nice to deliver a gift prior to the engagement dinner to her house. Otherwise, you could ask the attendant at the front desk to hold the gift for you until the end of the evening. You could then give it to the hostess upon leaving the club.
