Native here, and heck no to the long sleeves. Shoot I didn’t even pack jeans for our July trip in 08. Dh slipped in 2 prs, lord did I laugh at him.:laugh: Only time I get chilly is right out of the pool at night, and that doesn’t last long. I also live further south than Disney in Southwest Florida, 2 hrs south of Tampa so at 85* 110% humidity at 9pm is a wee bit hot even for me. The humidity will suck the breath out of you at times too. Maybe 1 shirt in case you are a person who tends to get cold easily. For my family, nah.
I’m also going in June and there is no long sleeved shirt, jacket, sweats, or jeans on my To Pack list.
BUUUUTTTT…I’d plan an extra outfit or 3. I plan on that since the humidity can kick your butt and you sweat through the cloths on your back by 11am and by 3pm you just want new fresh clothes on. :happy: July 08, July 07, June 06, June 05 all my extra outfits were used by day 4 or 5. Good thing we left on day 4 or 5.
