No, you cannot take the bathrobes from a cruise ship without being charged for them. Unlike the small toiletries (shampoo, soap, lotion) which are intended for guest use and can be taken home, bathrobes are considered cabin property, similar to the towels, bed linens, and pillows. Most cruise lines, such as Carnival, Royal Caribbean, and Norwegian, provide a price list in the stateroom or a tag on the robe itself indicating that if the item goes missing after disembarkation, the cost (typically ranging from $50 to $120 USD) will be automatically charged to your "Sign & Sail" or onboard account. If you truly love the robe, you can usually purchase a brand-new, wrapped version from the ship's gift shop or even order one from the cruise line's online boutique after your trip. This ensures you get a fresh item rather than a used one and avoids any awkward "theft" charges on your final bill. The same rule applies to the heavy "pool towels" provided by the ship; always ensure they are returned to your cabin or the designated drop-off point to avoid a per-towel replacement fee.
