My only concern would be the weather and hot it may be. You're getting married around May, right? (not so good with the months and the math; lol!) We got married at the end of April, at the Yacht Club. We walked around the lake and ended up at the Boardwalk (so we did the same walk, but looped around the other side). By the time we got there, I was pretty hot, and my feet were a little sore.
It definitely can be done distance-wise; just be aware that it may get a little warm for ya!
