Is there any danger if i travel outside the resort ?
OP, you'll probably be more "in danger" venturing out of your house in your city/town than outside a resort in Cuba... Nah... in general and in comparison, Cuba is a very safe country.
BTW, very funny #s 1 & 2!!

If "any danger" is interpreted widely, there are a couple of dangers particular to Cuba that you might deliberately expose yourself to as calculated risks; it's part of the Cuban experience.
If you use the same type of transports as Cubans use, trucks roughly converted for people transport, they are less safe than public transports in first world countries. The same goes for riding on the back of a motorcycle. Generally, traffic is not safe in Cuba, decrepit cars and a fair share of drunk drivers, as well as drivers with an attitude, so don't cross any street or road carelessly. A Cuban driver honks and expects you to leave his trajectory; if you don't he'll hit the brake in the last moment and if you're unlucky, it's the day his brakes give up.
In most every respect, a bit of street smartness takes care of the rest. Cuba has pickpockets, Cuba has robbery, but not to any larger degree than other places, and you should apply the same precautions as at home (regardless of where "home" is).
The most imminent danger is that you'll fall in love with the heap of crap that is Cuba, and maybe even more fall in love with one of the inhabitants, we are many that did that...

Honestly, I think there are more dangers WITHIN the resort, especially for your mental health.

Are you insinuating that staying in those resorts with 100's of sun starved Canucks, guzzling faux mojitos by the Tim Hortons cupful and sporting blotchy scarlet "tans" is anything less than a little piece of heaven?
OP
If you aren't troll then relatively speaking, Cuba will one of the safest countires you will ever visit. Unless you count constantly being shortchanged/overcharged a danger. And what rigger said.
If you are a troll please look out for the flying cocodrilos.

Yes, of course! Roughly the same danger one faces in getting out of bed in the morning. In fact, I'm not sure how safe it is to stay IN bed, since two of my (US) friends were raped when they were at home, in bed--one with her parents asleep upstairs!
Here's the real problem: LIFE IS A DANGEROUS PLACE. If you want to play it safe, don't try it--anywhere.

The biggest danger is in never wanting to go back to the resort, and in all the scheming and hand-ringing you'll do to get back to Cuba after you get home.
That post invited almost the exact same reaction from a wide variety of posters, all of which were delightful.
I strongly agree with gray when he chastised yorgos for suggesting that sharing the company of a bunch of pasty pink barato Canucks might be harmful to one's health. Hell, one might even get lucky and bump into cubaking !!!
