Certainly!! I do. I never travel without my laptop and smart phone. I usually have a GPS and my digital camera too. You have to have all the play toy's. :)
Laptop NO. Why would you want to be stuck to a screen when you should be out there enjoying yourself and doing things you don't normally get the chance to do!
Then after you've gone out and done some activities, you could update it all on share pictures of it on twitter or Facebook on your phone...but there is no need for a laptop, a camera maybe but nothing more.
Unless of course you want to work...then go ahead but personally I think just go on holiday and enjoy it because life is too short to be sitting there glued to a screen ,think about all the wonderful things you'd miss. I'm normally glued to my phone but I'd feel guilty after that things have gone on in the world and I don't know about and I feel as if I've missed out, and that people are getting on with their life and there's me on my laptop, not taking advantage of the choices I have. Well that's how I see it! Each to their own they say. 8)
