Pre-reception canapes and drinks timing?

Our ceremony is at 3 pm, I'm guessing it will go for about an hour, and our reception starts at 6pm. Everything will be in the same place, so our guests will have around 2 hours ceremony and reception. One hour of pre-reception canapés and drinks is all we can afford. We thought that we could have the canapes between 4:30 and 5:30, that way the guests are only left doing "nothing" for 30 mins at a time. However, the wedding coordinator at our venue thinks its best to have the canapes 5pm - 6pm, as she thinks that having a drinks "break" of 30 mins before the reception is weird. I think it's weirder to have a whole hour in which the guests are doing nothing after the ceremony, but I could well be wrong. Thoughts?
