This was not my experience up until October 2020. They were open 8-8, seven days per week during peak season but their hours were shorter over the winter. The valet launch they charged for was in the event you wanted them to launch your boat for you the prior evening (unattended by you) and tie it up at the dock so you could get out earlier than 8 am or if you got in late and left your boat tied to the dock for them to put away in the morning. You had to leave them an extra set of keys to enable them to do this. Alternatively you could launch before they closed and tie it up yourself. The moorage rate covered a launch and retrieval every day. If you were a pain in the butt coming in and out multiple times per day they would want to charge you for the extra service. I found that coming in right before closing was busiest but they are efficient at what they do and even being the 6th or 7th boat would only cause a wait of 15 mins or so.
Not only do you not need a trailer (you can boat straight in with prior arrangements) they don't have anywhere for you to park it. When you show up wanting to launch you can either drive your vehicle to your boat's rack and load up or have them bring it down off the upper racks and put it in a temporary rack for you to load up. Once you've parked your vehicle they put your boat on their trailer and you board and launch with the trailer. They go in far enough to soak your drive and you give the driver a thumbs up when you're running and engaged in reverse then they go in further and you reverse off the trailer. When returning the process is just done in reverse: you drive your boat on their trailer and they pull you out and put your boat away. It is a slick service but like anything there are pros and cons to it.
Pros:
No bottom paint needed, no scum line or growth on your boat, no bad weather or wakes slamming your boat against a dock, boat can't sink (general piece of mind), no trailering, no boat ramp chaos, location (central to great boating waters), secure storage, fresh water at boat storage spot, parking spot, fuel dock etc..
Cons:
Expensive but they have staff running the forklifts and tractor for launching/retrieving, only one parking spot per customer and extra pay lot above was closed for Covid last year, and restrictive launching/retrieving hours (you can still access your boat 24/7).
