Wedding Puzzle Hunt: Puzzle 1

My friends asked me to organize a puzzle hunt as a "morning activity" for their wedding day. Guests grumbled and pouted when I announced that they'd be solving puzzles at 10am (most had hangovers, which didn't help). In the end, though, they seemed to have a good time and, as I told them that evening when we handed out awards, all complaints that I had overestimated them had to be weighed against the fact that most groups finished all the puzzles in the time allotted.

Here's the first of the puzzles they found in their packet (I've cleaned up the instructions). All the answers led to somewhere in Victoria's Inner Harbor, and each team (which matched up to table assignments) had to bring back a souvenir from each spot to prove they had been.

Instructions: In each row below, insert a letter into the blank so that a 5-8 letter word stretches from somewhere in the left column to somewhere on the right. For instance, you could put an A into the first row to spell "BEATING." There are multiple answers for each row, but only one combination will spell out your destination. Post-game lessons: This spot goes by multiple names.
