A few years back we went on a great Carnival cruise through the Caribbean. A typical part of the daily routine was to head to the musical dance club at night, and to follow that up with a visit to the 24 hour pizza joint on the top deck prior to retiring for the evening. We were far from the only folks in our age range who more or less lived by this ritual while on the high seas. It was a great and informal setting to get to catch up with fellow cruisers and see how their excursions in port went. Not to mention, the pizza was absolutely delicious!
