You usually do not have to walk all the way to the salt water pool. Unless it's rough, you can just go straight into the water at the ladder at the end of the walkway from the dive shop. no more than 100 feet from tank pick up to the ladder. The concrete is a bit rough in spots so you need shoes or booties.
If you go boat diving with one of the west side operators, it is pretty much valet. They will pick you up at your condo at the beginning of the trip, set up and break down gear as well, and rinse and store daily. You would never need to pick up a tank and only have to haul the rest of your gear on first and last day.
