Go early, this place gets crowds, but for good reason; it was a great experience. Lots of great information and seeing the crown jewels exhibit was a highlight for everyone. There are benches, bathrooms and small refreshment stands on the courtyard, but you may want to bring some food and water. Plan for a coupe of hours here at least. The hop on hop off boat stops right at the tower. And several bus companies have stops just above the tower (big bus, etc). Hope that info helps you on your visit!
