Yep that does seem to be the pattern, but why not confirm that? I think the additional gripe though is that initially only a very small amount of parking is on sale, and then in the week leading up to the game randomly appears. Why not just communicate up front two sales windows rather than...
FFS - why can't they give a little more notice of on sale dates!?? wasn't on the site when I bought parking for Roma yesterday morning! At least usually more becomes available a week or so prior to the game, but really not sure why they can't be more communicative about this.
