I do not follow your post. With Wishes came 10 in-park sites, the same 10 in-park sites were used up to the last showing of Wishes in May 2017. There has only been one site outside the berm which was upgraded in preparation for Wishes in 2003 and was expanded about 9 years ago. The larger diameter shells were shot from the same location throughout the run of the show.
Of course there are the perimeter sites used for special shows and special events. These were only used for Wishes during the MVMCP in the days before Holiday Wishes debuted. Wishes has had perimeter fireworks a handful of other times as well for either private shows or special occasions such as the 40th anniversary of the Magic Kingdom park. Recently some of these sites have become semi-permanent along World Drive, North of the Contemporary Resort. The rest are on small trailers that are positioned when needed. One of them for the 360 degree shows is a small floating platform in 7SL.
