[Discussion] Any advice for integrating a dog into an apartment already full of cats?

My girlfriend and I are going to be moving in with her sister later this week, and I'm wondering what's the best way to get our dog and her cat's living together happily?

Our dog is a husky / lab mix who has a ridiculous amount of energy because we run him constantly. Her sister has two cats. One is "small and shy" and the other one is "fat and grumpy".

Things we have going for us

1. The dog has lived in the town we're moving to before. So it should be nice for him to fall right back into his old stomping grounds. As such were not really anticipation to much moving anxiety or anything. Pretty much the first thing were gong to do when we get him into town is take him out on a hike through his favorite trails.
2. While it's only a two bedroom apartment, there is a basement. So it shouldn't be to hard to create some separation if we need to. It's obviously not an ideal situation, because we would all feel bad locking him away like he's some monster, but it's better than him getting scratched because he's feeling his running addiction kicking in and he's starting to get antsy.
3. Their parents have graciously offered to watch the dog for a few day's while we get situated. So it's not like we're going to be doing all the "moving stuff" and all of the "pet stuff" at the same time. They have even mentioned the possibility of doing "weekday / weekend type thing until they get used to each other", but to be honest we kind of consider that a "last option" because their parents live two hours away. We hope that if it all goes well that we will just be able to get them integrated right, especially if we have a few day's to prepare for it.

Any advice, anecdotes, or portents of doom would be greatly appreciated. Thank you.
