Looking at Google Maps and recalling as best I can how much land was cleared and being prepped, it extended down to where the Dragons maintenance path cuts under Ice, maybe a little closer to the fortune teller/psychic tent. I could see them removing the games buildings and moving the Hogsmeade arch/entrance down the path to just before the small domed building across from the current games. That would allow the line and station for the Hogwarts Express at that end to be inside of Hogsmeade without as much issue (both thematically and physically). The current exit path on that side for Sinbad would end right where the psychic tent is right now in that scenario, maintaining one path into Hogsmeade on that end.
