Hi guys
I brought my laptop last year as I was going for a long time, I carried it in my handluggage, I had an almost mini suitcase with me my laptop and handbag both inside given most airlines permit only one piece of carry on baggage.
I would advise you when going through security to remove it from the case, pop it into a tray with the lead, and the rest of your baggage in another tray/ straight onto the belt. In my experience electricals are almost always checked, this will just save time they can take it away to be checked if needs be without making you open your bag yourself.
Most bars have wifi access too and don't mind if you bring your charger and adaptor. Means you can have a nice efes while you get on with your work in the shade
enjoy your holiday !
