The cheaper ones are near the airport.
It's not a Hilton but a Hampton Inn which I think is a part of the Hilton chain. Just because it's a Hamton Inn doesn't mean it isn't nice because it is very nice and very clean. The breakfast bar has everything in the world to eat. Definitely won't go away hungry. It's located at 7424 Northside Dr. In North Charelston. It is literally about one minute from the interstate that takes you right into downtown. Phone # is 855-271-3622. Hope this helps.
This property is a Hampton Inn, a part of the Hilton chain. Generally speaking, the Hilton Hotels are more expensive than Hampton Hotels, but I don't have any specifics. You might try searching the Trip Advisor web site.
