That sounds like a plan!
The other place besides Barcadera / public landing next to the sand / salt piles where there were good flats at low tide was the inlet / bay near Savaneta. You can see the road flare off to the south in this map:
The water was kind of deep there at high tide but would be good at low for bones and there were birds working bait off in the distance so a kayak would put you into some action for sure with jacks, small tuna, cuda, maybe even a wahoo.
The Barcadera area is also a low tide spot, and a local told me there are tarpon in that lagoon.
The bones around Malmok (the wreck) are here today, gone tomorrow but when they cruise by they are as willing as any I've ever cast to. Get the rod tip high quick, the coral will eat your tippet.
The beach is sandy to the south of the wreck with more coral to the north. Of course when I was horseback riding with my better half the fish were cruising the sand, and when I went back with the rod they were on the coral.
Just working that beach around Malmok for a couple of hours a day gives you better odds than the casinos down the road.
Good luck and please take some pictures to add to the Aruba Bonefish Club gallery.
