When do you sail?? I leave for our first cruise the last week of July with 5 kids under 10! So I am debating big time on what to take and not take. My sling is a given for my 8mo old we don't leave home without it anywhere. But I also have one that just turned 3 and with trying to keep everybody safe and close by I was thinking of taking the umbrella stroller so I can wear one with the other strapped in and hopefully my older ones will be able to hold on to the stroller. Good point about the sand though... any chance its like airlines and kids board first??? I'll report back on how things worked for us!
