Even just considering the entrance fees to Shimabara Castle and Shimeiso, which are must-see sights in Shimabara, this package is a bit of a bargain. Renting a bicycle allows you to explore a much wider area, so I recommend it, and there are significant discounts on bicycle rentals, so if you're going to rent one, you should definitely take advantage of them. There are also various other benefits. I didn't get to take full advantage of them because I only saw them on the day, but I think it's a good idea to check the benefits in advance.
