I always advise wife of the cooler atmosphere inside the rides and resturants and to maybe bring along a sweater but she says, for the short time she's in there, its not worth carrying all day and from early am to when the sun starts to really heat up, around 10, its not worth it. Evening are alittle different because the suns going down and the cooler air plus A/C can be chilly with them string type tank tops. Also depends on the month you're going, summer, no sweather, fall and winter, probably in evening, spring.... a toss up.
