I hope you enjoy your vacation. Nice weather, no income tax, and awesome gun laws. The only drawback is that there is no open carry, an option that would really come in handy in a climate like that. Is a trip to a range on the itinerary? Make sure you post some pics.
P.S. As long as you don't have any stops scheduled in PRNYC or PRDC you'll be okay. In fact, if your flight includes stops in any of those cities, get another flight. I'm serious; I've read numerous horror stories of passengers getting arrested in PRNYC for having guns in their luggage, even if they were declared and completely inaccessible to them while in flight.
