This was my second time on the Epic. I went back for the fact that I am a solo traveler and the studio rooms are perfect for me.
Rooms - The studios are small (duh) but perfectly adequate for me and the funky lighting was a cool touch.
Solo Lounge - This is great - every day there would be a happy hour where the solo travelers would mingle. This was a major selling point for me (Listen up other cruise lines!!!)
Studios were great for solo travelers. Make sure to get one away from the crew stairwell/elevator. These are louder!
