What to bring

We're going on our first overnight trip next month. Nothing too far away but it's about a 2 hour drive from where we live. I got us a king size bed for our hotel room and we will all be co sleeping together.

We'll be bringing a stroller but what else should we be bringing and packing?

I called the hotel and said their crib is a standard crib and not a pack and play. I had thought about bringing one just in case we have to put her down but it seems like that's just a lot to bring when we're only staying one night.

Also, by then she'll be one so in terms of milk and food how will that work out?
