My wife and I enjoyed our 4 nights on the Shook Up Shark during our first trip to Charleston, SC. Description and pictures were accurate and left no surprises on our arrival. Joel was very accomodating and friendly, and responded promptly both before and during our stay when we had to contact him even though it wasn't a time sensitive inquiry. Charleston itself was fantastic, it was pretty easy to walk into any restaurant and find a great meal. We used a couple of Joel's restauarant recommendations and they didn't disappoint.
I'd recommend the Shook Up Shark to anyone looking for something a little fun and different on their vacation. The only point I'd remind people to consider is that although it's a large yacht, some aspects of the living quarters (e.g., shower, doorways) are smaller than what you're used to. At 6'1" 185# I didn't have any issues, but I found myself thinking that a few inches taller would make things a bit uncomfortable.
