As for the rabbit holes still being rabbit holes, EA didn't say that they would be anything different. Please keep in mind that this is just a Stuff Pack. If they were to change the rabbit holes into something our Sims could enter, it would mean major programming changes to the game. That's simply not going to happen with a Stuff Pack. A stuff pack is exactly what it says... stuff. Only an Expansion Pack would even have a possibility of changes like this, and even then it's not a guarantee.
