I have mostly shorts and tank tops for the kids (2 and 4) and a pair of sandals and sneakers for each of us, 2 swimming suits, 2 PJ's ONE pair of pants for each and one jacket or sweater for each. Aside from the matching shirts, raingear and that kind of thing... what should we add? Are we going to be too chilly at night? Should I pack more long pants or long shirts... are tank tops too chilly for each day? We'll be leaving tomorrow and coming back next Friday. Thanks!!
