The best tip I can give for anything Prague Castle-related is to plan on spending two half days there. I say this because it will be VERY crowded in the mornings, however, your tickets are good for two days. So, if you go in the mid to late-afternoon, you can still visit three or four locations before they close up, and you can return the following day to finish up your tour. That's the best way to visit this attraction.
The grounds are large, and there are buildings just everywhere. You can't get into all of them, but the ones that are open, and that are included on your ticket are worth seeing.
I admit to (still) being more than a little confused as to how "Prague Castle" relates to the complex of buildings on the grounds. I'm pretty sure we visited everything that our tickets allowed us to visit (we got the second-highest ticket), and I know I was suitably impressed by every building and the different exhibits within.
However, I had been expecting a castle - something along the lines of Edinburgh Castle - and this was not that. It is impressive, I'll give it that. It's just not at all what I had imagined.
So, the complex itself is worth your day, but I do reiterate the tip above - go later, utilize the two-day option - otherwise you'll be shoulder-to-shoulder with tourists from around the world. And if you have my luck, you'll get the rude tourists who don't give a rip if they're stepping on you or constantly running into you. But that's just my luck.
There is plenty to see here, and they do offer audio tours (for a fee, and it's time-bound, so don't dawdle). Plus, there are shops dotted all around the grounds, so if you ever think, "I really wish I could buy a(n) [insert item here]...", chances are you won't be too far away from a shop that can sell you said item.
Worth a visit, and worth the climb. Heck, we even saw the band that Rick Steves followed around when we were leaving the Castle one day. You just never know what you'll stumble upon.
And those views!...
