I read the reviews on this site, and they just got me more confused.
I'll start by admitting that I am just a crass, shallow tourist, not really interested in dry facts, names or dates (By next day I forget them anyway). I want to visit the castle, be impressed, and be entertained. so, with that in mind...
1 - What time of day to go - early morning? Sunset? (recommendations are all over the map)
2 - Pre-arrange a guide? Hire one at the entrance? Audio-tape? no guide?
