I rode west-bound in May, and camped half the time.
You are correct that there are several locks with some level of facilities. I don't believe any have showers, but many have portable toilets, and some have potable water.
Lock 15 is great - water, facilities, and even electricity.
Lock 20 is good - no potable water, yes on facilities.
Lock 21 is lovely, but without any water or facilities. It's also pretty remote, so you can't just pop into town.
Lock 30 had water, but no facilities in May. Might be different now, since two years ago they had them.
Lock 21 allows free camping at the lock. I'm guessing if you called the Marina, that wasn't the Canal system lock; hence the $20 fee.
You are allowed to camp any any lock, pending approval from the lock master, but there will not be any services.
We added a couple of hotel stops so we could have a shower twice on the ride.
Enjoy your ride!
