Hotels in Downtown are Very Expensive. I recommend staying across the bridge in Mt. Pleasant or near the airport and taking a taxi/Ride Share to the port. Below are a few hotels downtown that are within walking distance.
1. Indigo Inn
Distance to Cruise Port – 0.5 Miles WALKING DISTANCE TO PORT.
2. The Spectator Hotel
Distance to Cruise Port 0.3 Miles NO SHUTTLE BUT WITHIN EASY WALKING DISTANCE.
3. Meeting Street Inn
Distance to Cruise Port – 0.5 Miles WALKING DISTANCE TO PORT.
