Gift for baby shower hostess???

MJ
My aunt, who is like a sister to me is hosting my co-ed shower on the 29th of this month. I don't know much about the event except it will be catered and so far we have invited roughly 65 people. Does anyone have any suggestions of a great gift we can give her to show our appreciation? I was thinking of maybe getting her a spa package or something like that...
I'm open to any suggestions. Thanks!
