Yea I’m definitely keen on getting a guide and making sure I take full advantage of actually being there and learning. I’ve wanted to go for a while. I had a look on the site, but there were 2 options available which I couldn’t tell the difference between, but one was cheaper than the other by 5/10 zloty... so I panicked and didn’t book...
I just need to try and figure out the best way to get there, but based on what @Rodders said, it might be possible to arrange that through the hotel. (Which we haven’t picked yet).
I hadn’t thought about the salt mines - we were only going for 2 days, primarily for Auschwitz, but I might have to try and fit it in.
