Fewer sanitary pads - turns out they supply everything, so I only needed enough for the trip home - and more pairs of sweatpants or shorts, plus an extra bathrobe. They do offer laundry, but I liked to have spares handy. 🙂 Ditto extra slippers. No matter what the paperwork says, you don't need lube, underpants (except to go home), towels, or other medical kit.
Lots and LOTS of entertainment you can do one-handed. Books, tablet, e-reader, games, whatever. You end up spending a lot of time in bed (we *can* get up, it's just so uncomfortable that we mostly didn't at first), plus dilation takes up a surprisingly long time at first.
