Don't count on having wifi at your slip. My husband has gone to the front desk and asked a couple of times about what's going on with it. Each time they've been surprised there's a problem or said "Yes, there are problems". Their best suggestion was to take our things and go to the Captain's Lounge and use the wifi there. I'll carry the Roku and my husband can carry the TV. Please don't mind me in being in my PJs.
My husband said I'm to harsh. The other facilities are nice and the staff is great.
Update: All is well that ends well. This story ended well. The marina is actively working on upgrading their wifi to 5G.
