Please visit! There is a lot to do here, from walking tours to trolley tours to boat tours of the harbor and Fort Sumter, museum houses, plantations and gardens. Patriot's Point has a Medal of Honor Museum, submarine, Coast Guard cutter, aircraft carrier with airplanes, and a replica of a Vietnam base camp.
The hotel you are considering is a great location within easy walking distance of the historic area, the waterfront, and great restaurants.
The weather is pretty mild here, though we may have some cooler days in February. The average high/low for February is 61/40 according to the weather service.
If you have any questions, please ask.
