I'm trying to decide if it's realistic for my husband and I to bring only carry-on bags next months when we revisit CN. I mean, mostly you're wearing bathing suits, right? How many 3 o. containers of liquids and gels can one realistically fit into a quart Ziploc bag? Enough for a week for an (ahem) not-so-low-maintenance kind of girl? It just seems easier (and cheaper!) to bypass checking bags. Anyone do this?
