Annie, it is HOT HOT HOT!! Trust me! I never wore long or even 3/4 sleeves during any of our 14 days!! On occasion I wore a light sweater to dinner or in the theater on the ship. I took mostly short sleeve t's and it was a decision that I regretted. Aside from the days we had to cover our shoulders (Sicily & Rome), I wished that I had tanks to wear for the duration (I did pack a few nice ones, but not near enough). My favorite things to wear during extreme heat are sundresses and I wished I had taken a few!
BTW WRT charging electronics in Barcelona - I never used the flat iron (as evidenced by my hair in the photos

) and the DS stayed in the safe. I regularly charged my IPhone, IPad and cameras with the thing that someone mentioned on
Amazon (the $4.99 adapter and extension cord). Never had a problem and the extension cord worked really on the ship for extra outlets (until my hair dryer blew the fuse and I didn't realize I could reset it

; good thing I packed an extra extension cord!)!!
