Yes, they have no sleepaboard option since you pay for a furll day just to get on the boat by 5. They did work with us on adding an extra day, but talk about sticker shock! Nothing like expecting a sleepaboard price (which we've done at Moorings in the past) and realize you need to pay for a full extra day!
I met a GREAT Lagoon sales guy at our local boat show, and he gave me his card so I can give him a report on CatCo. He said his potential owners are always asking for opinions on charter companies, so I said I'd send him a trip report once we return.
