If ya can afford it try the Embarcadero. You can more your boat overnight and be ready to go. They have a private fish cleaning station complete with crab cooker for their guests.
As far as secure storage, what's that? I worry about parking at home with my survelance system and alarms...
Here is a link to a hotel search in that area...
Newport Hotels
It lists the price ranges and if you search you can list dates and it will show availability.
Prices range from $40.50 to $239 plus tax etc of course. At least that's how I read it. See for your self.
I hope this helps...
