If I can make a suggestion -
I dive Venice with my daughter sometimes and I've found it makes it a much more pleasant dive if I bring a hand truck and wheel down to the end of the boardwalk at Service Club, then I walk the tanks and weights to the surf and allow her to gear up at/in the water. She's tough, but I notice she gets fatigued from the tanks more easily than I do (she still outbreathes me once in the water). Same goes for my wife. As for location, Service Club is longer, but the boardwalk makes for an overall easier trip with the hand truck and has some integrated tables that make for nice staging areas to stack gear prior to entry. Sharky's and S. Brohard entries are pretty easy if you get there early enough to get a good parking spot (or drop your stuff at the entry then park).
I'm generally a firm believer in everybody hauls their own gear, but make an exception for my daughter and wife in the interest of making their experience (ergo my and the overall experience) better. By using the hand truck, the double load on me is reduced (an even bigger difference when there's a long haul through parking lot or boardwalk as at Blue Springs). If you're in decent shape it's worth the extra work to make it a more enjoyable experience - you'll definitely sleep sound come evening too.
