I don't think the puppy poo palace would make a difference, other than making your pup sleep right next to her piddle pad when you aren't supervising and if she is locked inside the crate.
I personally would not train a pup to go inside a crate (unless it was an open crate used more in a cat litter box like way).
What kind of pads are you using?
When you can supervise, make sure you praise her when you see her hit the pad. Never stop praising. Give her a small treat too. When she misses, say "Uh oh" and clean up the mess without being upset.
Place her on the pad several times a day, right after meals or vigorous play, and right when she wakes up. Use keywords like "Go potty here." She may not need to potty, so let her go.
Make sure she is never to far from her pad even when you are home.
You can also try starting out using 2 or 3 pads lined up to make the target bigger. As she improves, eliminate 1 of the pads.
