Great, and I'm going to go for my vacation to Sharm el-Sheikh, this July.
They usually don't hit the same country twice at least I haven't seen it happen yet. Just be wary of your surroundings and stay safe that's all you can really do. Hey who would have thought on a beautiful morning here in NYC we would be hit? No place is really safe so you might as well go where you want and just be wary.
This is one of those "when your number's up" moments. However, the odds are probably on your side, unless things get significantly worse in the near future.
The biggest problem is that terrorism results in the closing of public spaces, massive security, and a very apprehensive attitude among your companions and even among the locals. It's a difficult question.
Be safe. They have some nice scuba diving there.
