For people that have 2 or more floors, do you have more than one changing table? If so, what do you use outside the nursery - a pack n play? a regular changing table? a changing pad on the couch? Do you have a duplicate of everything in the nursery (changes of clothes, hamper, diaper cream/hand sanitizer/etc), or a pared down version?

We have a 4 floor townhouse with living room/kitchen on floor 2, and bedrooms on floor 3. I'm assuming we won't want to take baby up and down the stairs for every changing, but I'm curious how people handle this.
