And we always bring Dixie *to go* cups to bring our coffee with us in the morning.
And we pack assorted sizes of ziplocs, premeasured tide in small ziplocs and then combined into a larger ziploc, bounce, flip flops, sharpie, pillow cases and fitted sheets (can't stand the flat sheets shifting around), packable rain parkas/anoraks. And usually baby wipes--still useful even with my babies grown up.
