coral house outside ceremony

hi guys! i went to see coral house yesterday and was impressed with their price and the rooms. only concern i have is having the ceremony outside. was the traffic noise any problem for any of you who had the ceremony outside?
also, the BM didn't tell me about the rooftop CH. do you have to have a certain # of people to use the rooftop? thanks in advance for your input.

I went to the coral house for a wedding MANY years ago -- we're talking like 10+ years - but the ceremony was outside and one of the only things I remember about it is that the ceremony was outside and
1) it was freezing
2) there was a highway behind the ceremony site... I can't remember if I actually heard the cars or just saw them though.
