Centerpieces: Blue dyed orchids submerged in water with floating candles on top. Marbles and LED light at the bottom of the cylinder vase. Loose orchids and blue votive candles on the table. I did not do these myself but easy DIY!! Decorator: Elegant Affairs

This with yellow orchids and dephinium (blue flowers) Very elegant
Submerged arrangements like this can be stunning and cost effective. We could do a mixture of something like this, only as you suggested, with more vases (I think 5) on each table, for half of the tables, then fuller low centerpieces for the other half. And candlelight all around! Also, these could be repurposed to line the aisle during the ceremony.
