Good question, I don't think so though, I've seen some up to age 44 working with us (which is considered ancient by our department. Imagine working somewhere in your 40s where everyone else is a college-age kid spreading cooties
) At opening time it will almost immediately be thrown in the rubbish bin! This is when managers lurk at their most! Closing time would be the best option, especially just after midnight. What might work as well would be during Open House periods in a space, or while everyone is on the island at Castaway Cay there's usually 1-2 forlorn counselors stuck on board. Sneaky works best - you can imagine we can never readily accept anything up front. And if you're very unlucky, you'll get one of the rule-stickler CMs who will gladly toss it in the rubbish bin and report anyone trying to retrieve it!
(By the way, you're my hero for putting so much thought into it! Every ship might be different, so if I was sailing as a guest I'd casually bring it up with a CM during Open House and see what they thought.
) Oh May's a bit far off for any of us to know where we'll be, really! I'm in between contracts right now technically, on vacation!
