I don't recall there being a microwave in our room at the DLH! We do bring snacks for the kiddos, and backpacks are easy to take on most rides, but we leave ours on the stroller so I can't say for sure. Most of the time, I way overpack on snacks and end up lugging it around. But water, we take a lot of. And we usually pack some capri-suns for the kids too! Have fun, how exciting that you will be there tomorrow!
