It's a good mile or more. There is the DASH bus which is free plus there are pedicabs you can hire in the market area.

No. Did not know. Thank you.

A lot of homes and inns are around the Battery. Few of the closest John Rutledge House and Elliott House Inn. They are within 0.5 miles. The Battery Carriage house is across the street. Very beautiful and one of the most haunted locations in Charleston. So the stories are told.

The city closes the actual park around dusk during the tourist season, but the sidewalk along the river is always open. For safety's sake, I would not be there past 10 at night.

Yes, but it stays busy during the spring and summer. Logistics will be difficult for chairs and other supplies. Doubt they would allow foods, and the homeless will join the other guests. You could hire a local transport co. for your guests, as parking will be a problem. There are many nice locations for weddings all around Charleston that would be easier.

Parking along lower Ashley River side is free. No charge for the park. No bathrooms except along E. Bay St. just past the Yacht Club.

It depends on what "tour" your carriage gets when you are ready to leave the barn. Every carriage is given a ticket, randomly, and that dictates what areas your carriage will travel....in order to keep traffic flowing. I would not suggest you take a carriage ride, but instead take the Downtown Shuttle over there and walk back to the Market Area and get a snack.

The subject of restrooms in the vicinity of the Battery and White Point Gardens on the Charleston Peninsula is of great interest, given that this is a strong tourist area. Although the original question is an old one, the subject is always of interest to those walking around old Charleston. Today I took a walk down to the Battery which is very lovely, and at the White Point Gardens there is now a sign and a map showing the locations of all the public restrooms in the area and near the waterfront. The closest restroom is at the Hazel Parker Playground, very near the Carolina Yacht Club and the Historic Charleston Foundation if you're using a map app. The restrooms are very clean and there is a lovely security "guard" named Albertha who monitors the restrooms (2 stalls) who will happily and enthusiastically answer any questions you have about Charleston. It's worth the trip!
