I have lost count of the number of ships I have been on and, to date, I have never seen a lilo or anything resembling one in a pool. Knowing the size of pools on a ship two lilos would normally cover the whole surface, excuse me, I’ve got to stop typing to laugh. ……….Ohhhhh that’s better. Did you think that you might pack one or two to use? .... Neil.
The nearest thing I have ever seen to a lilo is childrens arm bands !! A lilo would take up too much of the pool and you would find yourself the object of derision and fury from fellow passengers.
Although no lilos in pools, if you are travelling to the caribbean there are lovely beaches where you may enjoy using a lilo.
