Charleston Marriott
The sunset views from the balconies of this river-view hotel get better the higher you go—they're wonderful from the seasonal rooftop Aqua Terrace bar and lounge, where drinks and tapas are served. A glamorous glass addition with a cascading waterfall houses the concierge desk. The pool area is fringed by plenty of palms, and a fitness center has a wall of windows to let in the sun.
