If you go by ferry to Comino Island, then you can see from this photograph that there is not a lot of room to do either.
In the background you can see two mobile food/drink outlets, one of them is an ice cream van.
You may also be aware from this photograph that there is no shade, so be careful of the sun.
When the tour cruise boats, and the ferry docks, there are scores of people jostling for position.
However, it is quite an experience to visit Comino and the Blue Lagoon, so do enjoy if you ever go there.
Favorite thing: Comino is a small island between Malta and Gozo. I did not put foot on the island this time, but that's how it looks from the boat on my way to Gozo.
