I've never been but have always wanted to go. I say go alone and leave your itinerary with your family and friends, or join a tour group if you'd like company! Life's too short to sit at home and if you have the means and the time, go for it.
absolutely! just stay somewhere safe , travel smart and safe. but there are so many sites to see and so much shopping to do. you'll have a great time.
I do alot of things alone too cos if i sat around and waited for multiple schedules to sync, i'd never do anything!!
and the nice thing about doing stuff alone is that you can do whatever you want. no need to eat something you hate because someone else wants to eat it... no need to shop at a boutique you're not interested in bcos it's someone's fav brand.
