Ok, this might be stupid, but..... for the "party" Saturday night that is poolside, do you think the hotel will have heat lamps out there? I'm trying to minimize what I pack for the flight, but I don't want to freeze, either......
They probably will, but I wouldn't count on them being effective. I was at a cocktail party in LA this fall where we froze our butts off in spite of heaters!
Just carry your jacket/sweatshirt through security. They won't ping you for this. Just remember to remove it prior to walking through the metal detector.
