Not exactly in Greece where you’ll be but when I dove Corfu with CorfuScubanauts they dropped the wives off at a bar/grill while we did the first dive, we joined them for lunch during the surface interval and then picked them up after the second dive.
The biggest surprise was that they were wearing more thermal protection than I brought for the deeper dives, I did it in a 3 mil but was chilled. Like a NJ dive but with better viz and much older junk on the bottom.
