As a non-girlie girl who did the full girlie girl wedding I say go for the mountains !! My brother did a lovely ceremony for just 8 of us in the mountains and it was really nice.
As for dresses...they are both gorgeous. I found when I was dress shopping that the ones I liked on line and on the hanger I hated when I put them on. The one I liked the best was picked out by someone else...of course being the frugal person I am I got on-line and bought the the gown as a sample gown from a store that was going out of business. I had it steamed and it was good as new.
