Escort Card Dilemma

My original plan to have vases with my escort cards has been shot down, and for good reasons. If we passed out the escort cards like this during the cocktail hour, how would guests hold those, their drink AND get some hors d'oeurves. Quite a handful.

My dilemma now is, what in the world do I do with the 200 vases that I've purchased? We had originally planned on having the vases filled with baby's breath, but now I'm rethinking that whole idea. What I've come up with is this:

Since the tables will be relatively clutter free because we aren't having a seated dinner, what if we put round candles inside the vases and placed one at each seat? This would add some ambiance to the room, decor to the tables and each person would still have something to take home. But, then, how will the guests know that the vases are theirs to take? Should I still put name cards on them so they will know that the vases are theirs?

We will still have the escort cards setup at the entrance, mainly for crowd control. We are a little worried that some family and friends will bring uninvited guests, so we are going to have someone monitoring the escort card table and welcoming the guests to (hopefully) ensure that the only people at the wedding are invited guests.

So, now I ask for your help. What do you think would be a good idea to do with the 3" cubed vases/votive holders that we've purchased?!?
