Here, the hardest thing to get right was the shape of the "7" created by the seven C's. Only a few well-known seas have a "C" in them. And, the location of the C's within those seas are fixed. Thus, it took many iterations to whip this puzzle into shape (hah!).
Of course, there's still always flexibility. I originally submitted a grid with CASPIAN and CHINA swapped and with BLACK one row lower. That version had some limiting fill constraints (e.g., _ _ LN in the upper-right from CORAL and CASPIAN), and I had to rework the puzzle to remove them.
That said, the current configuration is still pretty constrained. There are three downs (BEANIE, ROBOTIC, and RELEASE DATE) that intersect three themers and 10 more that intersect two themers. And in four of those 10, the two fixed letters are consecutive (which are typically harder).
I'm lucky that SEVEN SEAS and CARIBBEAN are the same length and that CARIBBEAN is a good candidate for the top-left point of the 7 glyph, which means SEVEN SEAS can be symmetrically placed as a revealer. If that hadn't worked out, I would have used a stacked SEVEN/SEAS revealer in the lower-right corner.
If you ever visit Horseshoe Falls, allow plenty of time to find parking. When we went, all the lots were full and it took quite some doing to find an open space. Unfortunately, we had a flight to catch that afternoon, so we could only run to the falls, take a quick peak, and then hustle back to the car. Next time, I'd like to meander over to the Canadian side, check out the "Cave of the Winds" viewing area behind Bridal Veil Falls, and ride the Maid of the Mist.
