To Wishing Well or Not To Wishing Well.... that is the question.

We have been living together for a while so we don't need much. Therefore i figured we do a Wishing Well Wedding. My mother is ol' school and thinks it's tacky. I found a cute little poem but fellow event planners say drop the poem and be specific about what we are requesting or keep the poem but advise underneath that we are requesting monetary gifts. I thought about just leaving it out but i don't want to end up with a bunch of stuff we don't need or want. I did start a gift registry but i can't get past 20 very expensive items. What are your thoughts?
