We were just there last year with Olivia…yes there was some military presence but no more than I've seen in Mexico and other Caribbean places…I guess when you're use to seeing them you just don't pay much mind and they have never made me feel uncomfortable.
Excursions were fine and going to Casinos and off resort restaurants…we had no problems.
jaedesmom is correct in saying that Olivia would not put us in harm's way…and yes do give them a call!
We just returned from the cruise to Russia and many people were fearing going there…yet the place was great and so were the people…very large military and police presence…but there were no problems at all…we had a great time!
