I just did a Regal shop and saw The Greatest Showman. It was really good. The shops are very easy, but I don't do them as often because my husband doesn't like the theater (there's no stadium seating). If possible, choose a movie that has been out a while and maybe an early showing (like 4pm). It's much easier to do a head count this way. Though I have also done the shop on an opening night. You can count seats left open or do your best guess, you just need to explain why your count could possibly be off (many patrons entering/leaving at the same time, etc). I have always been able to watch the entire movie and successfully complete the shop. Plus, free concessions and my guest has a free ticket too. Can't beat free entertainment.
