We had all these great song choices picked out, especially for the processional, but once we had a meeting with our WC upon arrival, we realized that a big part of the traditional hawaiian ceremony is the blowing of the conch. So, if we were to do music during the processional, it would have overshadowed the blowing of the conch (which is blown slowly 3 times during the processional.) I'm glad we did it this way, b/c it lent some hawaiian culture to our wedding in Maui. Just a thought, but as far as the waves drowning out the minister, the waves where we were located (Kaanapali) were not big enough to make enough noise to drown out much of anything; just some nice background noise Hope that helps!!
