Oh, Yeah. Prices will go up. My slip in Pensacola is north of $500. We are tucked away in Bayou Chico and fairly well protected. After Hurricane Sally in 2020, slips are difficult to locate.
Personal Knowledge:
We spent three days on a weekend at Bear Point Marina in Orange Beach. Sportfishermen go past this marina headed to the gulf and make the marina rolly.
Barber's Marina in Elberta, AL used to have a breakwater but Hurricane Sally......
Big Lagoon has several marinas on the north side only because the south side is a National Park. But these are also along the path to the gulf for sportfishermen so you need a marina with a breakwater of some sort.
If you find a slip in Bayou Chico, try to get one close to shore. Pensacola Shipyard is building a dry stack for FIVE HUNDRED boats of 50 foot or less and I expect traffic to get worse as people have various ideas of "No Wake".
We stayed in a marina on the Fly River in Mobile Bay for a while. Huge amount of water to sail in but it reminded us of Galveston Bay. Between the Mobile River and the ship traffic, the bay stays roiled up and dirty.
I know of a couple of other marinas but I have not visited them so I won't give an opinion of them.
