It wasn't bad, but it definitely wasn't swimming weather.
Wasn't El Nino 2000, though? We're hoping for better this year. Hoping, but not counting on it....packing a little of everything, leaning heavily on shorts, capris and t's, with a pair of jeans each and a sweatshirt...that ought to cover it. Don't panic and pack huge....you're not off in the boonies, a load of laundry as a possibility is probably better than two or three extra suitcases.
I've started throwing my kids clothes for each day in large ziploc bags....I just toss it on the bed in the morning and say "Here you go, get dressed." Then I have another set in a bag with me in the stroller to use after Kali River Rapids or Splash Mountain or whatever....
Leaving a warm change of clothes in the locker's not a bad idea, either, if you don't have a stroller/pack mule...
