Pretty boring. Tried to do a snorkeling excursion, but it was canceled due to high winds (which happens a lot apparently). They were very nice and gave us a refund and we ended up going to the free beach. It was very busy and not very clean -- the whole city is industrial and pretty shaken by hurricanes dating back to 2002. Clean it up already!
The shopping was nice -- a lot of jewelry, cubans are available, cute place for souvenirs.
