5. Stocking up on products

Luxury ships and some river cruise lines stock their cabins with high-end products from brands that are considered a splurge (think Bulgari). You can even sometimes find full-size bottles that will last you the length of your cruise and then some, like the Etro products on the new Crystal Esprit. But maybe want more than just what’s left in the bottle to take home. Start by charming your cabin steward, gushing about how much you love the scent. They might just refresh them daily, sending you home with a suitcase full.
