I wouldn't let H1N1 stop me from traveling anywhere and it's not proven, as far as I know, that it's even hit C.C. It's flu season, period, everywhere around the world. Frankly, I'd rather have it and get it over with. I don't know where "up here" is but I know that where I am, yes, there are murders far more regularly but they are normally confined within the group of people who tend to use guns, knives, etc. on each other. And frankly, two violent crimes (or more) on a tiny island is a lot more threatening and scary than several in a huge city where the chances of me being targeted are slimmer. And I don't want to go for a vacation somewhere where I can't relax in safety with my friends and family. That's the big appeal of C.C. and the only thing that justifies paying the higher prices to be there (as opposed to other islands). So...C.C. really needs to address this with the police force, quite simply. These latest violent crimes did not take place in the middle of the night when everyone was under lock and key (though many other crimes have and do). So although you may want a place with burglar bars, that's not the only issue you need to be aware of....crime is higher on the island overall and C.C. needs to act fast or it will be another tough year for tourism if not longer.
CC condos near the split and Seaside Cabanas were pretty safe, if I remember correctly....but best to ask the hotel owners directly what kind of security they have. Ask for pictures as proof.
