Soon they were running in and out of the water like old pros.
There was much burying in the sand, of course, because you can't come to the beach and not have a parent bury you in the sand.
There were even jellyfish, which didn't get anyone until day 3. I was afraid they would scare the kids away from the water, but they came back the next day with just as much excitement, so I think my tactic of telling them they could use it as an impressive beach story worked. (You can tell your friends you've been stung by jellyfish! Isn't that cool!)
At the end of every day, we loaded the kids up with beach gear and either walked the half-mile back to our cabin, or waited for the tram, if the time was right.
