Re Lock, it was dark when we got there, i could not read the numbers because of wearing glasses and the light from my torch reflected offvthe numbers. My partner had ti get down on her knees and finally managed to open the lock. Maybe a digital lockmin a more amenable place would work.
I would suggest that a curtain reaching the tiles innthe shower would prevent a lot of water getting out near the door.
I hope you take these as constructive suggestions.
We loved sitting almost on the water
